THE BIG INTRO Big U is a disk packed with U-tilities that increase ProDOS's performance. You Applesoft programmers, beginner and experts, will love using Big U's powerful machine language routines and commands in your programs. And every Appler can have fun customizing ProDOS and using Big U's utility programs.

HAVE FUN WHILE YOU LEARN

This manual assumes that you have a basic understanding of loading and saving files, cataloging a disk, and so on. We have done our best to keep things simple, so even if you're a raw beginner, be patient with your Apple and have fun! If you don't have Apple's "Basic Programming With ProDOS" and "Basic Tutorial" manuals, run out and buy them.

If you're an old DOS 3.3 veteran starting to explore ProDOS, you'll be surprised by some things, but you shouldn't have any real trouble. See page 72 for a summary of ProDOS commands. If you're interested in the advanced technical aspects of ProDOS, get the book, "Beneath Apple ProDOS" from Quality Software.

EXECUTING BIG U PROGRAMS

All BIG U programs are run by typing "-filename" (that's a hyphen followed by the program's name).

BACK IT UP! Big U comes from the factory unlocked and unprotected, giving you the freedom to inspect its programs and to copy them from disk to disk. Make a duplicate of your original so that any exotic experimenting or accidents won't ruin the original. Big U's FILE.MOVER program (page 19) can make copies file-by-file, or any disk copy program will copy the entire disk. (Our favorite is DISK.COPY from Beagle's "Extra K" disk.) Please don't get carried away by giving copies of our disks to your friends. Every illegal copy is a vote for copy protection and against friendly software. You support us and we'll support you.

PATH NOT FOUND? If ProDOS is giving you "Path Not Found" errors every time you try to load a file, you are probably having prefix problems. See your "BASIC Programming With ProDOS" manual to learn more. The best suggestion we have is to type "PREFIX/" to cancel the prefix before loading files.

Since the Big U disk doesn't have any subdirectories, you shouldn't have many Path Not Found problems with it, unless you spell a file name wrong.

BEAGLE EROS RECOMMENDS If you are new to ProDOS, we highly recommend Apple's book, BASIC PROGRAMMING WITH ProDOS.

If you are an advanced programmer (or would like to become one), we highly recommend Quality Software's book, BENEATH APPLE ProDOS.

CRT.WRITER CRT.WRITER is a combination Applesoft/machine language program that allows you to write and print short letters or memos and do quick jobs like address envelopes (if your printer can handle them). It also allows you to easily create elaborate title screens which can be saved on disk and used by your programs.

This "screen processor" is so committed to the What-You-See-Is-What-You-Get philosophy that each document can be viewed in its entirety without any scrolling, page-flipping or disk access. Of course, each document is only one screen long, but what did you expect?

ONE PROGRAM, TWO FILES Make sure you copy both of the files, "CRT.WRITER" and "CRT.CODE" if you want to move the program onto another disk.

GETTING STARTED Type "-CRT.WRITER". The copyright message will soon be displayed in the middle of the screen. Press any key to get started.

To create a screen, you can just start typing. The Return key and arrow keys do about what you'd expect them to do. Don't forget though, that you're limited by the space on the screen.

APPLE-KEY COMMANDS To issue a command, you must hold down the left (or "open") Apple key while pressing another key. To simplify things, we'll just call open-Apple the "Apple key" from now on.

CRT.WRITER COMMAND SUMMARY OA = Open (left) Apple key BA = Both (left and right) Apple keys MOVING THE CURSOR: OA-0 (zero): To top left of screen OA-1… OA-9: Reposition in current column Arrow keys: Move one character or one line OA-left arrow: To left-most character in line OA-right arrow: To right-most character in line Tab: To next tab position OA-Tab: To previous tab position SCROLLING THE SCREEN: BA-up arrow: Screen up (rulers must be off) BA-down arrow: Screen down (rulers must be off) MOVING TEXT: OA-L: Left justify current line OA-C: Center current line OA-R: Right justify current line OA-D: Duplicate a block (leaves original) OA-M: Move a block (erases original block) DELETING TEXT: (Press Apple-Delete the indicated number of times.) 1: Clears from cursor to end of line 2: Clears remainder of line 3: Clears all lines below the current line 4: Clears the entire screen DISK COMMANDS: OA-K: Catalog drive 1 BA-K: Catalog drive 2 OA-G: Get screen from disk (load) OA-S: Save screen to disk OTHER COMMANDS: OA-A: MouseText on/off (if available) OA-I: Inverse text on/off OA-P: Print the screen OA-Q: Quit and exit to Applesoft OA-T: Toggle tab rulers on/off OA-U: Undo changes (if still possible) OA-V: Toggle vertical typing on/off OA-X: Credits

Apple-0: CURSOR HOME Pressing Apple-0 (zero) puts the cursor in the upper left corner or "home" position of the screen.

Apple-1… Apple-9: RELOCATE THE CURSOR Pressing Apple-1 through Apple-9 proportionally positions the cursor vertically on the screen without changing its horizontal position.

Arrow Keys: MOVE THE CURSOR The Arrow keys move the cursor about like you'd expect. Try all four of them.

Apple-Left/Right Arrows: JUMP LEFT & RIGHT Apple-Left Arrow jumps the cursor to the left-most character on a line, while Apple-Right Arrow, logically enough, moves you to the right. Spaces do not count as characters.

Both Apples-Up/Down Arrows: SCROLL THE SCREEN To scroll the screen up or down, hold down both Apple keys and press the Up or Down Arrow key. Scrolling is not available with the tab rulers visible. (Press Apple-T to turn the rulers on and off.)

Return: CARRIAGE RETURN Just like on a typewriter.

Apple-C: CENTER A LINE Pressing Apple-C will center the line of text that the cursor is on. The left and right-most characters on the line determine how it will be positioned. If you are creating a screen that will have borders, center the text first. If you make your borders first, no positioning commands will have any effect.

Apple-L & R: LEFT & RIGHT JUSTIFY Pressing Apple-L or Apple-R will position the line of text at the cursor to the far left or far right of the screen. The border note under "Apple-C" (above) applies here too.

Apple-V: VERTICAL TYPING This command is especially useful for title screen creation, but it is also suitable for creating acrostics and acronyms. Press Apple-V and the cursor will change to a "^". All text will now be typed vertically. Press Apple-V again to get back on the level.

To make a simple border, use inverse spaces (press Apple-I first) and use vertical typing to enter the sides. You might want to make the sides two characters wide so the thickness is comparable to the top and bottom rows.

Apple-Delete: DELETE TEXT Pressing the Delete key alone simply prints a block character on the screen. Apple-Delete, however, clears varying portions of the screen, depending on how often it is pressed. Press Apple-Delete once to clear text from the cursor to the end of the line. Press it a 2nd time to clear everything else on that same line. Press it a 3rd time to clear everything to the bottom of the screen. Press it a 4th time to erase the entire screen. In other words, to erase the entire screen, hold down the Apple key, and press the Delete key four times. Accidental deletions may be undone (see "Apple-U: UNDO"). Note: This command uses the "Delete" key. Don't confuse it with Apple-D, which is used in duplicating blocks of text.

Tab & Apple-Tab: TABBING Press the Tab key to move the cursor to the next tab setting (indicated on the tab rulers at the top and bottom of the screen). Existing text will not be affected. Pressing Apple-Tab moves the cursor back to the previous tab stop. Note: The tab settings cannot be adjusted. Another Note: Tab is the same as Control-I.

Apple-T: TAB RULERS OFF/ON Pressing Apple-T turns the tab rulers at the top and bottom of the screen on and off. These rulers are primarily useful for helping you "eyeball" the position of the cursor. Note: You can't type over the tab rulers. To use the top and bottom screen lines, turn off the rulers first. Restoring the rulers will temporarily hide your text, but won't erase it. Note: The screen scrolling commands (page 11) will not work with the tab rulers on. Several other commands automatically turn the rulers off.

Apple-I: INVERSE TEXT Note: Inverse text will be sent to your printer as normal-looking characters. (Don't blame us; blame your printer.) Pressing Apple-I toggles inverse text mode (black on white) on and back off again. Try it and see. Depending on your Apple, you may not be able to display inverse lower case. Turn on MouseText (if your Apple has it; see below) to get inverse lower case.

Apple-A: APPLE MOUSETEXT Note: MouseText text will be sent to your printer as normal-looking characters. (Don't blame us; blame your printer.) Pressing Apple-A toggles MouseText off and on if you have an Apple IIc or an enhanced (newer-model) Ile. MouseText. upper-case characters are graphic symbols (see the back of your Peeks & Pokes chart). Lower-case characters will appear as inverse lower-case. "FGFGFG…". (But wait: Apple has announced that they will be eliminating this little feller from future Apples. If you don't see him on your screen, that's why.)

Apple-D: DUPLICATE A BLOCK To duplicate a block of text on the screen: 1. Put the cursor on a corner of the block you want to duplicate. 2. Press Apple-D. A number "1" will mark the spot. (You may press Esc at any time to leave the duplication mode.) 3. Move the cursor (now a "2") to the diagonally opposite corner of the block to be duplicated, and press Return. 4. Move the cursor (now a "D") to the upper-left corner of the block's future location and press Return. The entire block must fit at the new location. A beep means that the limit has been reached. For example, if you're duplicating a block 80 characters wide, you'll only be able to move the "D" cursor vertically.

Apple-M: MOVE A BLOCK The procedure for moving a block of text is virtually identical to that for duplicating, except that the original block of text is erased. Substitute Apple-M for Apple-D in step 2 above. The cursor in step 4 will be an "M" instead of a "D".

Apple-U: UNDO A MISTAKE You may press Apple-U to undo screen changes after certain operations. Apple-U must be pressed immediately after the change has been made (that is, before doing anything else). It works after the delete, move and copy commands, and after screen scrolling and line positioning. Although it's great for undoing mistakes, Apple-U also comes in handy when you want to see how moving or copying a block affects the screen, without committing yourself to the new layout.

Apple-P: PRINT THE SCREEN When you want a "hard copy" of the current screen display, just press Apple-P. CRT.WRITER assumes that your printer is in slot 1. You may press Esc at any time to stop printing. MouseText and Inverse characters will be printed as normal characters.

Apple-K: CATALOG THE DISK Press Apple-K to catalog (katalog?) drive 1. Hold down the right-Apple key too if you want to catalog the disk in drive 2. Technical note: If you want to let CRT.WRITER catalog a subdirectory or the RAM disk, change variables K1$ and K2$ in line 5 of the program. K1$="" would catalog the current directory, K1$="/TEST/SUB" will always catalog the SUB subdirectory of disk "/TEST" and so on.

Apple-S: SAVE THE SCREEN When your masterpiece is complete, press Apple-S and you will be asked for the screen name. Enter a legal ProDOS file name (or full pathname) like "TITLE". You may specify slot and drive values if you want (like "TITLE,D2). Be sure to use a unique name so you don't overwrite screens that are already on the disk. Saved screens are identical in format to those created with the SAVE.80 program (page 71). To load a screen called "ABC", simply type "-ABC" from Applesoft, or use this command in a program: 10 PRINT CHR$ (4) "-ABC"

Apple-G: GET (LOAD) A SCREEN Press Apple-G to show everyone why you worked on your computer all weekend. When you're asked for the screen name, type in the name you used to save it. After the screen is loaded, it can be modified and resaved under another name (or the same name if you want to erase the old version). Screens created with the SAVE.80 program (page 71) may also be read by CRT.WRITER. Apple-Q: QUIT Although you'll probably never want to use this option, it may be necessary from time to time. Press Apple-Q, and you will be asked if you want to quit. Type "Y" followed by Return to exit to Applesoft. Any key but "Y" will let you stay in CRT.WRITER.

ONE MORE THING… Feel free to use CRT.WRITER to create screens for any programs that you write. We simply ask for a little credit. Just acknowledge your use of CRT.WRITER in the documentation and send Randy Brandt and Bert Kersey 75% of your gross sales. 25%? 10%? Oh, never mind…

FILEMOVER FILE.MOVER is a fast, user-friendly program for copying files, formatting disks, and handling other file operations such as deleting, renaming, locking and unlocking files.

Unlike Apple's FILER, this program does not require BASIC.SYSTEM to be reloaded, or lengthy pathnames to be entered. It has the edge on the IIc System Utilities disk because it is faster, takes up much less disk space (under 30 blocks compared to 151 blocks!), and is compatible with the RAM disk. Only FILE.MOVER has options to view files, move files, and to format disks with more than 35 tracks.

GETTING STARTED Type "-FILE.MOVER" or select it from Big U's main menu. The current date and time (if available) will be shown near the top right of the screen. Below that, disk directories [A] and [B] are identified with their slot and drive values. All file handling is based on these two "working" directories. They may be different disks, or subdirectories of the same disk. Use option N to change them. FILE.MOVER Options begin on page 23.

ENTERING NAMES WITH FILE.MOVER You will only have to type a name if you are creating a subdirectory or renaming a file or directory. On these occassions, the following rules and features will apply: - You are forced to start with a letter A-Z. - You are limited to 15 characters. - Spaces are automatically converted to periods. - The Delete key erases the character to the left of the cursor and "pulls back" characters to the right. - Control-Y erases all characters to the right of

the cursor, including the cursor position.

- Regardless of the cursor position, you may press

Return to accept the name shown.

- Esc cancels the entry. (Pressing Esc nearly

always gets you out of unwanted situations.)

PRINTING THE FILE.MOVER SCREEN Press Control-P at almost any time to dump the text screen to a printer in slot 1. If the print-out has some blank lines caused by extra carriage returns, run FILEMOVER.SETUP (page 31).

You cannot dump the hi-res screen in the VIEW option (page 24), and Control-P is ignored when FILE.MOVER expects you to type a file name. If your printer is in slot 2, type "PR#1,A$C200" before running FILE.MOVER.

SELECTING FILES WITH FILE.MOVER When you select certain file operations from the main menu, directory [A] will be read and its files will be displayed on the screen. For example:

Press Return after using arrow keys to select files to COPY, or press Esc

Moving the Cursor: The first file name will be highlighted in inverse (black letters on a white bar). Let's call that bar the "cursor". To move the cursor to other files, move up or down with the vertical arrow keys ("A" or "Z" for II+ users), or move from column to column by pressing Tab (or Control-I).

Selecting Files: Press the right arrow key to select the file name at the cursor. De-select files by pressing the left arrow key.

Press Control-A to select all files, ignoring previous selections. When all desired files have been selected in the proper order, press Return to let FILE.MOVER go to work. While the chosen file operations are going on, you may press Esc to quit.

Changing the Order of Files: A number will appear to the left of each selected file name. This determines the order in which file operations will occur, allowing you to organize disks by copying files in any order. To change a file's number, move the cursor to the file name. Deselect the file if necessary with the left arrow, and then type the first digit (1-9) of the new number that you want. A question mark will appear. Press the space bar for a single digit number, or enter the second digit. This option is designed for inserting a file into a sequence already selected. Previously selected files will be renumbered as necessary. If only a few files are out of order on a disk, select all files (see Control-A, previous page), then de-select the misplaced ones so that you can enter the correct numbers directly.

Viewing Large Directories FILE.MOVER displays a maximum of 29 files at a time; if a directory has more, "view next page" will appear in place of file 30. Move the cursor there and press Return to see more files. Another page will be shown with a "view previous page" option and (possibly) another "view next page" option. The limit is 95 files per directory. Files from 96 on will be ignored by FILE.MOVER.

FILE.MOVER OPTIONS C: COPY FILES FROM [A] TO [B] Press "C" to copy files from directory [A] to [B]. Select the desired [A] files from the menu on the screen. See "Selecting Files" (page 21). If you copy a locked file, both the original and copy will be left unlocked. Single drive users will be prompted as to which disk volume to insert as the copying occurs.

M: MOVE FILES FROM [A] TO [B] Press "M" to move files from directory [A] to directory [B]. This option is identical to the Copy option (above), except that the original file will be deleted. It is especially handy for grouping files in a subdirectory on a disk. Just move the files from the disk's main directory into the subdirectory on the same disk. The disk must have at least as many free blocks available as the size of the largest file being moved. Warning: Don't MOVE files to the RAM disk. Use COPY instead.

V: VIEW FILES ON [A] Press "V" to view a file on directory [A] in hex/ASCII format. When the file menu appears, highlight the desired file name and press Return to load it for viewing. Use the left and-right arrow keys to page back and forth through a file. Press Control-P to print the screen at any time.

The hex number to the left of each line is the offset of that line within the file. For example, the first byte on line I is at 0, because it is 0 bytes from the beginning of the file. The first byte on line 2 is $10 (16 decimal) bytes from the beginning, the last byte on line 2 is $1F (31 decimal) bytes away, and so on. Press Return to see how the file looks as a hires picture. It'll probably look like garbage unless you loaded an actual picture file. Press any key to get back to the text display. Press Esc to return to the main menu when you're finished viewing.

FILE.MOVER can load a maximum of 16 blocks (8K) at a time, so larger files must be viewed in several sections. When the end of a section is reached (every $2000 bytes), you are prompted to press Return to read the next section, or Esc to continue viewing the current section. Once you read a new section, you cannot return to the previous one unless you go back to the menu and restart with the view option. This "chunk-by-chunk" method lets you view massive 100K files like the main AppleWorks segment.

E: ERASE FILES ON [A] Press "E" to erase (delete) files from directory [A]. Select the doomed files from the menu (see page 21) and they will be ruthlessly destroyed. If files are locked, you will be asked for permission. Press "Y" to erase it, or "N" to grant a stay of execution. Note: A subdirectory cannot be erased unless it does not contain any files. L: LOCK FILES ON [A]

Press "L" to lock files on directory [A]. Select the files to be locked from the menu (see page 21) and FILE.MOVER does the rest. Note: You will not get an error if you lock a locked file or unlock an unlocked one. U: UNLOCK FILES ON [A]

Press "U" to unlock files on directory [A]. This option works similarly to option "L", above.

R: RENAME FILES ON [A] Press "R" to rename files in [A]. Select the files to be renamed from the menu (see page 21). Type the new name, or just press Return (or Esc) to skip the current file. If a file is locked, it will be unlocked anyway and you will be allowed to rename it. The file will remain unlocked under its new name.

A or B: SEE CATALOG OF [A] OR [B] Press "A" or "B" to directory [A] or [B]. As with normal ProDOS catalogs, you may press Control-C to exit early. Unlike normal, you may press the space bar to "single-step" through the file names.

N: NEW DIRECTORY ON [A] Press "N" to change the directory represented by [A] near the top of the screen. You will then have three options: A, D and N (or Esc to exit):

A: Add a Subdirectory Press "A" to read a subdirectory on directory [A]. A menu of disk [A] files will be shown. Use the arrow keys to select the subdirectory you want. Press Return to select the subdirectory, or Esc to exit. For example, if you select the SUBFILES subdirectory after reading the /DISK main directory, [A] will become "/DISK/SUBFILES".

D: Drop a Subdirectory Press "D" to drop the last subdirectory from directory [A]. For example, if [A] was set to "/DISK/SUBFILES", pressing "D" would change it to "/DISK".

N: New Disk Press "N" to read a new disk. Then specify the slot and drive you want. Enter the desired slot (1-6) and drive (1-2), insert the new disk, and press Return to read it. You will be returned to the main menu, with the new disk's volume name listed as directory [A]. Most Apples use slot 6 for disk drives 1 and/or 2. Hard disks are often in slot 7 or 5. The RAM disk is always slot 3, drive 2. Apple IIc Note: The "internal drive" is slot 6, drive 1, the "external drive" is slot 6, drive 2.

X: EXCHANGE [A] AND [B] Most options apply only to [A], so this option lets you move [B] to [A] with an "X" keypress.

S: CREATE SUBDIRECTORY ON [A] Press "S" to create a subdirectory in directory [A]. Then type a name for the new subdirectory (page 20). Use the "Add subdirectory" option if you want to use the newly created subdirectory on [A]. This option is useful for grouping files on a disk. Create a new subdirectory, choose it as directory [B], and then move files into it from the main directory on [A].

D: RENAME DIRECTORY [A] Press "D" to rename directory [A]. This option will actually rewrite the name on the disk. For example, you could rename /BIG.U, /LITTLE.U. Type in a new directory name (see page 20). If subdirectories have been added to [A], you may only rename the most recent subdirectory.

T: CHANGE DATE/TIME Press "T" to set the date and time. If your Apple has a clock, this option is unavailable. Use the left and right arrows to highlight the segment you wish to change. The day is always highlighted first, so pressing the left arrow would move you to the minutes, while pressing the right arrow first would highlight the month. Use the up arrow or "A" to increase the highlighted value, and the down arrow or "Z" to decrease it. All segments "wraparound" when the end is reached. A "No Date" option appears between December and January. Press Return when the date is correct, or press Esc to restore the date given when you selected this option. The date and time are not saved on disk by FILE.MOVER. Use the DATE.SET program (page 63) to do that.

F: FORMAT OPTIONS ("Format" means "erase", so be careful!) Press "F" for the format menu, then choose a format option. Press Esc if you want to return to the main menu.

RAM Disk Options (128K Apples only) I: Install /RAM Press "I" to format the RAM disk (or reconnect it if it was disconnected). D: Disconnect /RAM Press "D" to disconnect the RAM disk so that auxiliary memory can be used for other purposes (like Beagle Bros' Extra K disk).

Floppy Disk Options Formatting (or "initializing") a floppy disk allows ProDOS to use it for storing files. Remember, all existing information on the disk will be destroyed. The newly formatted disk will be named "/BLANK." It may be renamed to any legal name with the "Rename Directory" option on the main menu.

N: New Format Slot/Drive Values Press "N" to enter new slot and drive values. (Unlike other FILE.MOVER operations, diskette formatting has nothing to do with [A] and [B].) Enter the new values and press Return. F: Normal Format (35 tracks) Press "F" for a normal ProDOS format. This option works with all 5-1/4" Apple drives. They have 35 tracks which store 4K each, giving a total capacity of 140K, or 280 blocks. Directory information takes up 7 blocks, leaving 273 free for files. Press Return to format the disk, or press Esc to return to the menu.

GOING BEYOND THE 35-TRACK LIMIT Most Apple disk drives are capable of formatting 38 tracks, for a total disk capacity of 152K, or 304 blocks. All IIc drives, Ile DuoDisk and He UniDisk drives should work with 38 tracks. Many Disk II drives will work as well. Some non-Apple drives are even capable of formatting 40 tracks, giving you 160K of storage. FILE.MOVER has a special format option to format disks for 38 tracks. If your drives can handle it, you can change this option to anything from 36-40 tracks (see FILEMOVER.SETUP, page 31). The instructions are the same for all formats.

S: Special Format (38 tracks) Press "S" to format extra tracks. Press Return after the warning message. Esc returns you to the menu. The formatter cannot determine if a drive handles 35 tracks only, and will repeatedly try to "get at" the extra tracks. Open the drive door if you accidently try to format 38 or 40 tracks on a 35-track drive.

FORMAT ERROR MESSAGES If a formatting problem arises, you will get one of the following messages: Unable to format may be caused by a physically damaged disk or an incorrectly positioned disk in the drive. To avoid this, try slowly wiggling the drive door as you close it. Unable to format write-protected disk occurs if the write-enable notch on the diskette is covered, or if you try formatting on a non-existent drive like slot 3, drive 1. Don't try formatting a printer slot; you'll have to press Control-Reset. Unable to format due to bad drive steed means you might have to take your drive in to a dealer for professional service.

CREATING A BOOTABLE DISK ProDOS-formatted disks contain only directory information, leaving the rest of the space for data. The PRODOS and BASIC.SYSTEM files necessary for booting are not automatically stored on the disk. Follow these steps to create a bootable disk: 1. Format a disk. 2. From the main menu, select "N" twice to change directory [A] to /BLANK (the new disk). 3. Press "X" to swap directories. Directory [B] is now /BLANK. 4. Press "N" twice and make /BIG.U directory [A]. 5. Press "C" to copy files from /BIG.U to /BLANK. 6. Copy PRODOS and BASIC.SYSTEM. 7. Insert /BLANK in drive 1 and reboot. It should boot and exit to BASIC.SYSTEM.

ProDOS automatically runs any program named STARTUP after BASIC.SYSTEM is loaded. To make a simple STARTUP program, type "NEW" and enter this program:

10 HOME 20 PRINT CHR$(4);"CAT"

Now type "SAVE STARTUP" and reboot; this time your new disk will clear the screen and then catalog itself.

QUITTING FILE.MOVER Press Esc from the main menu. Verify your choice by pressing "Q" and you will be returned to Applesoft. Any previously existing program will have vanished, but utilities such as GPLE and ProDOS external commands above Himem should have survived.

CUSTOMIZING PRODOS 1.1.1 FOR EXTRA TRACKS ProDOS 1.1.1 is normally limited to 280 disk blocks (35 tracks), so it will ignore the extra 24 blocks on a 38-track disk. Here's how to increase its capacity for up to 40 tracks: 1. From Applesoft, type "BLOAD PRODOS,TSYS,A$2000". 2. Type "CALL -151". 3. Type "56E3:number" Replace number with 20 for a 36-track drive, with 28 for a 37-track drive, with 30 for a 38-track drive, with 38 for a 39-track drive, or with 40 for a 40-track drive. 4. Type "BSAVE PRODOS,TSYS,A$2000". 5. Type "3DOG" or press Control-Reset to get back to Applesoft. 6. Reboot to install the new extra-track version. It will still work properly with 35-track disks.

FILEMOVER.SETUP Use this program to change FILE.MOVER's special format option to anything from 36-track to 40-track formatting. Type "FILEMOVER.SETUP,D1" to get started. After FILE.MOVER is loaded, you may select the desired number of tracks. Some printers automatically do a carriage return after 80 characters are printed. FILE.MOVER normally does too, so you may get doublespacing in part of your printouts. To cancel FILE.MOVER's carriage returns, select option "P". Press "S" to save FILE.MOVER with the new values.

KEYCAT.80 KEYCAT.80 is a "file menu" program that lets you select programs from disk with only a couple of keystrokes. After typing "-KEYCAT.80" only once, you can access the file menu any time you want by pressing Control-Reset or by typing "/RAM/MENU". KEYCAT.80 CREATES MENU When you type "-KEYCAT.80" (see next page), you are actually creating a new file called "MENU" on the RAM disk (if you have 128K) or on a floppy disk (if you have only 64K).

IF YOU DON'T HAVE 128K KEYCAT.80 comes set up so that MENU will be stored in the RAM disk (slot 3, drive 2–128K required). If you have only 64K, stop now and Run the KEYCAT.SETUP program (see page 36). It will let you specify a new slot and drive for the disk that will contain the MENU program.

TO CANCEL CONTROL-RESET MENU is normally activated by pressing Control-Reset. If, however, you don't want our program messing with Control-Reset's normal functioning, stop now and Run KEYCAT.SETUP (page 36). It will let you prevent Control-Reset from activating MENU. Typing "-/RAM/MENU" will still do the job.

GETTING STARTED KEYCAT.80 is harder to explain than it is to use, so go ahead and use it and see what happens. Here's what you do: 1. Remember, if you don't have 128K, or if you don't want to use Control-Reset, use the KEYCAT.SETUP program first (see page 36). 2. Type "-KEYCAT.80" to create and install the MENU program (do this only once). 3. Bring MENU to the screen by pressing ControlReset, or by typing "-/RAM/MENU" (do this anytime you want to select a file). Note: Depending on your system and MENU's slot and drive location, you may have to type a command like "-MENU,S6,D1" or "-/RAM/MENU". 4. With the file menu on the screen, press Return to read a directory (see page 34) or select a file by pressing the key corresponding to the letter or number next to its name (below).

SELECTING FILES Once the files you want are on the screen, select one of them by pressing the key corresponding to the letter or number next to its name. Then you have three choices: 1. Press "R" to Run the file. ("Dir" files cannot be Loaded or Run.) 2. Press "L" to Load the file. ("Bin" and "Bas" files only). 3. Press Esc to skip selecting this file. If the directory has 36 or more files, press "Z" to view more files. Press "0" to get back to the first group of files.

READING A NEW DIRECTORY If there are no file names visible in the menu, or if you want to see files from another disk, press Return and select one of the options that appear at the bottom of the screen: Press "C" to read the current drive. This is the drive where MENU found the current directory. Press "O" to select any Other slot and drive. After you select a slot (1-7) and drive (1-2), the main directory on the disk in that drive becomes the Current Directory. (To select a subdirectory from that drive, press Return and then "S".) Press "M" to select the MENU drive. This is the directory where the MENU file is stored; either the RAM disk (slot 3, drive 2), or the drive specified by KEYCAT.SETUP. Press "S" to read a Subdirectory. This option only works if one or more Directory ("Dir") files are listed on the screen.

ERRORS When an error occurs, pressing Esc will give you a chance to "make repairs". Most errors are caused by leaving drive doors open, putting disks in upside down, or using DOS 3.3 disks. Only ProDOS disks are allowed. A "Device Not Connected" error when you type "-KEYCAT.80" means you don't have a IIc or 128K Ile, or your RAM disk has been disconnected. To reconnect, reboot or use FILE.MOVER (page 28). A "Path Not Found" error when you type "-MENU" probably means that you need to specify a slot and drive (for example, type "-MENU,S3,D2" or "-MENU,S6,D 1 "). A "Path Not Found" error could also mean that the floppy disk with the MENU program on it has been removed. Put it back in the correct drive when you type "-MENU". (128K RAM disk users don't have to worry about this.) HARD DISK USERS If you have a hard disk, use KEYCAT.SETUP to configure for the appropriate slot and drive, then make this your STARTUP program after running KEYCAT.80 to create MENU: 10 PRINT CHR$(4)"-MENU" KEYCAT.80 and GPLE GPLE, Beagle Bros' Applesoft editor, uses Control-Reset to reconnect itself. If you want to use KEYCAT.80 with GPLE, it's best to de-activate the Control-Reset option with KEYCAT.SETUP. Then you can add a GPLE "-MENU,S3,D2" Escape command to activate. Now a command like Esc-M will activate MENU and Control-Reset will still be available for reconnecting GPLE.

RESETTING RESET To cancel KEYCAT.80's grip on ControlReset, you can reboot, or type: "POKE 1010,0: POKE 1011,190: POKE 1012,27"

MENU SIZE LIMITATIONS The MENU program is a type "BIN" file that is 8 or more blocks in size, depending on the number of file names it contains. Its limit is 255 files. You can look at MENU (after you have created it) by cataloging the RAM disk (type "CAT/RAM") or the appropriate floppy drive.

KEYCAT.SETUP KEYCAT.SETUP lets you configure KEYCAT.80 to work with your specific system and preferences. Type "-KEYCAT.SETUP" to get started. You will be asked: 1. Whether or not you want Control-Reset to activate the MENU program. 2. The slot and drive where the MENU program will be stored. Follow the instructions on the screen and select your preferences. A little experimenting doesn't hurt, because you can always reconfigure the program later. When you are finished with KEYCAT.SETUP, it will re-Save KEYCAT.80 on disk. CONTROL-RESET OR -MENU? Normally, you press Control-Reset to activate MENU. This method is quick and easy, but has some drawbacks. It takes some room on memory page 3, and other programs may need to use that area. No Big U programs have any conflict with KEYCAT.80 or MENU. If you don't want to use Control-Reset, disconnect it. Now only the command "-/RAM/MENU" will activate MENU. This method is a little more cumbersome, but doesn't use any memory until MENU is actually activated. (MENU runs on hi-res page 2: $4100.6000).

SELECTING THE MENU DRIVE On 128K Apples, the RAM disk (slot 3, drive 2) is the preferable location for MENU. Otherwise you may put it anywhere you like. The most obvious choices would be slot 6, drive 1 or 2.

Big U's AMPER Programs Each Big U "AMPER" program gives you one or more new commands that begin with the the magic ampersand ("&") character (&STORE, &INPUT, etc.). You load or "install" each program in memory by typing a hyphen ("-") followed by the program's name. Once a program is installed, its new "amper-commands" are yours for the typing.

WARNING: LOAD ONLY ONCE! Each AMPER program costs you a little more memory, so don't waste saace by loading the same program more than once. You might want to write an installation program that runs only once. It loads the ampersand commands that you want, and then Runs the program that uses the commands. For example:

10 TEXT: HOME: NORMAL: REM RUN THIS PROGRAM ONLY ONCE! 20 PRINT CHR$(4);"-DUMP.80": REM LOADS BIG-U'S PROGRAM 30 PRINT CHR$(4);"-INPUT.80": REM LOADS ANOTHER BIG-U PROGRAM 40 PRINT CHR$(4);"-SCREEN.PRINTER": REM RUNS YOUR PROGRAM

"&" TECHNICAL NOTES: Each ampersand program installs itself above Himem so your programs don't overwrite it. When Applesoft encounters an "&", it jumps to location $3F5 (1013 decimal) and follows the machine-language instruction there–usually a jump (JMP) to another address. When the ampersand programs are installed, they save the existing jump-address at $3F5-3F7 before plugging in their own. This technique, known as "daisy-chaining", lets many ampersand programs reside in memory together.

APPENDER Install only once: Type "-APPENDER". Function: Joins two or more Applesoft programs. New commands: &STORE "hides" the program in memory so you can load in a second program. &RECALL appends the hidden program onto the end of the second program. Example: Let's call our higher-numbered program "HI.PROGRAM" and the other one "LO.PROGRAM". Be sure that the programs don't have overlapping line numbers. Renumber them if they do. There are several renumber programs on the market, including the one on our Double-Take disk. 1. Type "-APPENDER" (only if you haven't already). 2. Type "LOAD LO.PROGRAM" (unless already loaded). 3. Type "&STORE" to hide LO.PROGRAM. (A "Lowest Useable Line Number" message will appear.) 4. Type "LOAD HI.PROGRAM". 5. Type "&RECALL" to connect the two programs. 6. Type "LIST" to see the appended programs. This newly-created program can be run normally if the line numbers are in order.

ANOTHER USE FOR APPENDER &STORE can also be used to temporarily hide an Applesoft program while you run another program. Type "NEW" to get rid of the test program, then "&RECALL" to get your original back.

DUMP.40 and DUMP.80 Install only once: Type "-DUMP.40" for 40 columns or "-DUMP.80" for 80 columns. New command: &POP (stands for "Print On Paper") Function: Prints the text screen on your printer. Comments: &POP is fast because it doesn't waste time printing blank spaces at the end of a line. If you have an Apple IIc or Apple Ile with an 80-column card, you can use the new DUMP command instead (see page 48).

PROGRAM EXAMPLE: 10 REM DUMP.40 MUST BE IN MEMORY 15 PRINT CHR$(21): REM 40-COL SWITCH 20 FOR Y=1 TO 24: FOR X=1 TO 40: IF

X<40 OR Y<24 THEN VTAB Y: HTAB X:
PRINT CHR$(X+32+Y);: NEXT: NEXT

30 VTAB 1: REM ANY PROGRAM 40 &POP: REM DUMP SCREEN 50 REM CONTINUE WITH PROGRAM 80-COLUMN PRINTER PROBLEMS? DUMP.80 and the DUMP command (page 48) send a carriage return to the printer after every 80 characters. If your printer does this automatically and you are getting some kind of double-spacing, here's the solution:

1. Type "BLOAD DUMP.80" (or BLOAD DUMP). 2. Type "POKE 16385,0". 3. Type "BSAVE DUMP.80" (or BSAVE DUMP).

Note: DUMP.80 Requires 80 columns!

INPUT-40 and INPUT.80 Install only once: Type "-INPUT.40" for 40 column input or "INPUT.80" for 80 columns. New command: &INPUT Features: -All visible characters are acceptable as input, including commas and colons. -Control-characters are ignored. -Maximum string length is programmer-definable. The standard length is 20 (if someone hasn't changed it already). -Pressing Esc returns a null string (as in A$="") regardless of cursor position. -Pressing Return accepts the input as it appears, regardless of cursor position. -Pressing Control-Y clears from the cursor to the end of the line. -Pressing Delete deletes the character to the left of the cursor and closes the gap created. The left and right arrow keys are used normally. (If you don't have a Delete key, see next page.) Limitations: -String variables only (For numeric input, use the VAL function as shown in the examples). -Screen input only (&INPUT cannot be used for getting data from a disk file). -Insert is not available. Check the NOTES program; maybe we've added it by now.

Example: 10 REM INPUT.40 MUST BE IN MEMORY 15 &INPUT "TYPE YOUR NAME HERE (LAST, FIRST): ";A$ 20 PRINT "HELLO, ";A$;"!"

This example works whether or not the user typed a comma between his last and first names. Normal INPUT would have cut the name short at a comma.

INPUT.SETUP This program lets you change two key features of the INPUT.40 and INPUT.80 programs: 1. The maximum string length allowed. For example, you might want to limit someone to typing only a 5-character word. 2. The key to be used as the Delete key. For example, if your Apple doesn't have a Delete key, you might want to use control-D instead. Type "-INPUT.SETUP" and follow the instructions on the screen. When you are finished, a new version of INPUT.40 or INPUT.80 will be saved on disk.

POKING THE MAXIMUM STRING LENGTH Another way is to change the maximum string length is to do it with a Poke. For example, to change the maximum allowable &INPUT string length to 5:

1. Install -INPUT.80 or -INPUT.40. 2. Immediately let LOC=PEEK(1015)*256+7 3. Let MAX=5 (for a maximum length of 5) 4. POKE LOC, MAX PROGRAM EXAMPLE: 10 REM INPUT.80 MUST BE IN MEMORY 20 REM AND LOC MUST HAVE BEEN SET 30 POKE LOC,10: REM LENGTH=10 40 &INPUT "TYPE A WORD: ";X$ 60 POKE LOC,2: REM NEW MAX LENGTH 70 &INPUT "ENTER 2-DIGIT NO: ";TD$ 80 TD = VAL(TD$): REM CONVERT STRING

TO NUMERIC VARIABLE

90 PRINT X$, TD * 2: GOTO 30

REMOVE and REM.OVE.128 Install only once: Type "-REM.OVE". If you have 128K, type "REM.OVE.128" New command: &REM Function: Removes all REMarks from the Applesoft program in memory. Rem's are helpful when programming, but when a program is executing, they take up room and slow things down.

REM.OVE This program simply deletes all Rem's from the program in memory. Before you make any changes to your program, you will probably want to load your Rem'd version back in from disk. To use it: 1. Type "-REM.OVE" 2. Load an Applesoft program with Rem's. 3. Type "&REM" to remove the Rem's. 4. Run the program without Rem's. 5. Re-load the Rem'd version from disk. 6. Make changes to it. 7. Save the program back to disk. 8. To test it again, go back to step 3.

REM.OVE.128 This program also deletes Rem's, but it first saves a copy of the Rem'd version of your program, named "SOURCE" on the ProDOS RAM disk: Slot 3, Drive 2. From there, you can more-quickly retrieve your Rem'd version. To use it: 1. Type "-REM.OVE.128" 2. Load an Applesoft program with Rem's. 3. Type "&REM" to save the program on the RAM disk and remove the Rem's from main memory. 4. Run the program without Rem's. 5. Type "LOAD/RAM/SOURCE". 6. Make changes to the program. 7. To test it again, go back to step 3. 8. Save the program on disk. Warning: Never use REMOVE from within a program; weird things might happen! As Rem's are removed, you will see an "*" for each full program line eliminated, and a "." for each Rem dropped from the end of a line. When done, the total bytes saved will be printed on the screen.

GOTO WHERE? If you're in the habit of issuing GOTO's or GOSUB's to a Rem-only line, as in the sample below, insert a colon before the Rem before using REMOVE. 1000 GOTO 2000 2000 :REM NOTICE THE COLON. 2010 PRINT "HELLO" After Rem's are removed, the line will be left with only a colon (":") following the line number: 1000 GOTO 2000 2000 : 2010 PRINT "HELLO" Without the colon, the entire line would have been removed and you would get an ?Undef'd Statement Error when you ran the program. Actually, it would be more efficient of you to just GOTO the next line (you would save 6 whole bytes).

AND NOW A WORD FROM OUR SPONSOR "For the maximum in program compacting, including erased Rem's, shortened variable names and automatic combining of program lines, use Beagle's D CODE disk. See our catalog for details."

SUPER.POKE Install only once: Type "-SUPER.POKE". New command: &POKE Function: Allows an easier way to poke a range of memory or a string of numbers from Applesoft. A demo program resides semi-hidden on the Big U disk. Type "-COPYRIGHT. 1985" to see it.

FILL A RANGE OF MEMORY Syntax: &POKE start: end, value "start", "end" and "value" can be literal numbers or variables. 10 REM EXAMPLE #1: FILL A LINE 15 FOR X=0 TO 255 20 &POKE 1024:1063,X: NEXT 10 HGR: REM EXAMPLE #2: FILL HI-RES 20 VTAB22: INPUT "NUMBER (0-255):";X 30 &POKE 8192:16384,X: GOTO 20 POKE A STRING OF NUMBERS Syntax: &POKE start, value1, value2, etc. "value 1" and "value2" can be literal numbers or variables. This routine is useful for replacing lengthy For-Next loops which read Data statements and Poke in values. Example: &POKE 1024,193,194,195 prints "ABC" in on the screen. 1024 is the upper left of the screen. 193, 194 and 195 is ASCII for "ABC".

Big U's COMMAND Programs Each Big U Command .program gives you at least one new ProDOS command. All commands are loaded or "installed" by typing a hyphen ("-") followed by the file name. The new commands may then be used just like regular ProDOS commands–from immediate mode (the keyboard) or from deferred mode (within a program) preceded by PRINT CHR$(4).

WARNING: LOAD ONLY ONCE! Never load (or "install") the same command more than once. Not only will you waste memory, but ProDOS might hang up in an endless loop which can only be broken by rebooting. Type "-BASIC.SYSTEM" to start over and get rid of extra commands.

COMMAND SYNTAX Items in [square brackets] are optional. Items in UPPER CASE must be typed as shown. Items in lower case are parameters supplied by you.

ANYCAT Install only once: Type "-ANYCAT" New command: ANYCAT Function: Catalogs DOS 3.3 disks under ProDOS control. Syntax: ANYCAT [,S slot] [,D drive] Comments: DOS 3.3 deleted files will be displayed as file type "D". An inverse character will appear to the far right of each deleted file name. When the catalog pauses, press Esc to exit, or any other key to see more files. If a ProDOS disk is present, the normal "CAT" command will take over. If a prefix is set, it will be used instead of the slot and drive. Example: Type "ANYCAT,S6,D2" to catalog the DOS 3.3 disk in slot 6, drive 2. If a ProDOS disk is there, a "CAT" command will be executed.

COPY and COPY.1 Install only once: Type "-COPY" or "-COPY.1" Use COPY.] if you only have one drive. New command: COPY Function: Copies files from disk to disk. Syntax: COPY pathnamel, pathname2 Comments: "pathnamel" is the file to be copied, and "pathname2" is the file to be created. "pathname2" cannot be an existing file. COPY.1's COPY requires 2 full pathnames (both starting with "/"). COPY's COPY, however, will substitute the current prefix if you don't supply it (see last example on this page). Directory (DIR) files cannot be copied. You cannot COPY between disks with the same name. You may, however, quickly rename disks by typing a command like "RENAME /DISKA,/DISKB". Examples: Type "COPY /BIG.U/COPY, /MYDISK/COPY" to copy COPY onto your disk. Type "COPY FILE, FILE.A" to make a backup copy of a file on the same disk. In programs, you may use strings as pathnames: 10 PRINT CHR$(4);"COPY";A$:",";B$ With COPY (not COPY.1), you may take advantage of the current prefix. For example, there are two ways to copy TEST from /DISKA to /DISKB: 1. Type "COPY /DISKA/TEST, /DISKB/TEST". 2. Or type "PREFIX, D2" (DISKB's location),

Then type "COPY /DISKA/TEST, TEST".

DUMP Compatibility: See Comments below. Install only once: Type "-DUMP" New command: DUMP Function: Type "DUMP" to print the entire text screen to a slot 1 printer. DUMP determines whether 40 or 80 columns are being viewed, and prints accordingly. Press Esc to stop early. Comments: DUMP is compatible with Apple IIc's and most 80-column IIe's. Use the DUMP.40 program (page 39) if you don't have an 80-column display, or use DUMP.80 if your 80-column card doesn't work with the DUMP command. See page 39 if you get blank lines in your 80-column dumps. DUMP won't let you crop or print graphics. Use Beagle Bros' Triple-Dump disk instead. Example: Type "CAT" in 40 or 80 columns. Then type "DUMP" to send the screen to the printer.

EST (ProDos 1.1.1 only) Install only once: Type "-EST". New commands: ERASE, SPACE and TIME Type "ERASE" to effectively erase the Applesoft program in memory (RENEW should restore it), reset all Applesoft pointers and the ProDOS bit map, turn off 80 columns and execute NORMAL, TEXT and SPEED=255. ProDOS commands added after EST was installed will be lost when you type "ERASE". ERASE is similar to 3.3's FP command. Type "SPACE" to show the disk volume name and free space for the disk in the last drive accessed. Do not use this command from inside a program. Type "TIME" to display the time and date stored in memory. This command cannot change the values; to do that, use the DATE.SET program (page 63). If your Apple has a clock, you can use TIME in a program like this:

10 VTAB 1: HTAB 24: PRINT CHR$(4); "TIME": GOTO 10

HEX Install only once: Type "-HEX". New commands and functions:

XC: Hex/dec/bin converter (page 50)
XD: Memory disassembler (page 50)
XP: Register and flag displayer (page 51)
XS: Hex/Ascii memory scanner (page 51)

Comments: Any leading "X" is considered to be a command when entered from the keyboard, so type a colon before defining variables that start with X (not necessary from within programs). For example, with HEX installed, if you type "X=5", you'll get a ProDOS "Syntax Error" message. Typing ":X=5" will works normally.

HEX.H (ProDos 1.1.1 only) HEX.H is the same as HEX (above), but it "hides" inside BASIC.SYSTEM from $BB4C.BC79 so that no programming memory is used. HEX.H may be added to BASIC.SYSTEM so that it is installed when you boot, at no cost in memory: 1. Boot a backup copy of the Big U disk. 2. Type "-HEX.H" to install HEX.H. 3. Type "CALL -151" to enter the monitor. 4. Type "BLOAD BASIC.SYSTEM,TSYS,A$2000". 5. Type "454C<BB4C.BC79M" to move HEX.H into BASIC.SYSTEM. 6. Type "4707: 50 BB" to point the external command to HEX.H. 6. Type "BSAVE BASIC.SYSTEM,TSYS,A$2000". 7. Reboot and try some HEX commands. Negative numbers will not be shown in the result when XC (next page) is used with HEX.H, although negative numbers may still be entered.

XC (HEX command 1 of 4) Function: Convert a number to hexadecimal, binary, decimal and negative decimal. Syntax: XC [,E number] Comments: "number" is any decimal number from 0 to 65535, any hex "$" number from $0 to $FFFF, or any negative decimal number from -1 to -32768. Typing "XC" without a number will repeat the last number converted. HEX.H's XC will not convert to negative decimal. Example: Type "XC,E-151" to convert -151 to hex, binary, decimal and negative decimal. The same result would be achieved by typing "XC,E$FF69" or "XC,E65385".

XQ (HEX command 2 of 4) Function: Disassemble memory. This is an enhanced version of the monitor List command. Syntax: XD [,E address] [,L lines] Comments: "address" is the decimal or hex location where you want to start disassembly. "lines" determines how many lines (1-255) will be disassembled. Because a line can contain 1 to 3 three bytes, the actual amount of memory disassembled will vary. If you specify a large number of lines, you can pause the listing by pressing Control-S. Any key continues. Typing "XD" will repeat the last disassembly. Example: Type "XD,E$FBD9,L11" to see the speaker beep code. Continue viewing 11-line segments of memory by typing "XD,E address" only. Free Tip: To print a machine language listing, preview it on the screen using the XD command. When you see what you like, type "PR#1" and then "XD" to repeat the listing on your printer.

XP (HEX command 3 of 4) Function: Display the 6502 registers and flags. Syntax: XP . Example: Type "XP". The screen will show: A=04 X=8C Y=00 P=2B S=98

NV-BDIZC

P=00101011 Comments: AA and Y are registers; P is the processor status register and S is the stack pointer. The processor is repeated in binary. Its flags from left (bit 7) to right (bit 0) are: N (negative), V (overflow), "-" (unused), B (break), D (decimal), I (interrupt), Z (zero), and C (carry). Bits are considered set if 1, or clear if zero. For example, a BCS (Branch on Carry Set) instruction would branch if a "1" appears under the "C". The register values are taken from the storage area at $45.$49. To see what flags are set when P=9, just type "POKE 72,9" followed by "XP"; or type "CALL -151" followed by "48:9" and "XP".

XS (HEX command 4 of 4) Function: Scan memory in hex and ASCII. Syntax: XS [,E address] [,L lines] Comments: "address" is the starting address of memory, and "lines" is the number of lines displayed (independent of the bytes per line). XS displays 8 bytes per line on a 40-column screen, and 16 bytes per line in 80 columns. "XS" with no parameters repeats the last scan. Example: Type "XS,E$B878,L20" to see the ProDOS command table. Typing "XS,E address" will then continue to show 20-line segments of memory.

MON (ProDos 1.1.1 only) Install only once: Tpe "-MON" New commands: MON and NOMON Function: Turn ProDOS monitoring on and off

(similar to 3.3's MON and NOMON commands).

The MON command will echo the following ProDOS commands to the screen: CREATE, OPEN, READ, WRITE, CLOSE, FLUSH and DELETE. For text files, data being input after a READ or printed after a WRITE will also be shown on the screen.

CREATE, DELETE and OPEN will show the pathnames involved. The others will give the pathnames for the first two open files, and open files from 3 to 8 will be referenced by number.

Syntax: MON [,R rate] Syntax: NOMON "rate" is either 0 (zero) or 1. Use zero for continuous operation and 1 for single-step (press a key to continue). If NOMON has been used, typing "MON" will return to monitoring with the same "rate" setting used previously. Examples: Type "MON". Now type an illegal command like "CATS" to see ProDOS's "Close All", "Flush All" and "Syntax Error" messages. Type "MON,R1" followed by "CAT" to single-step through a catalog listing. Type "MON,RO" to return to continuous MONitored operation. . Type "NOMON" to turn off monitoring. IMPORTANT: Turn MON off, reboot or type "BYE" before using a SYS program like Apple's FILER. Why? Because MON intercepts MLI calls at $BFOO in the ProDOS global page. The original addresses are reset by NOMON, and by MON when "BYE" is used.

ONLINE Install only once: Type "-ONLINE" New command: ONLINE Function: Lists the current ProDOS volume names for each of your drives. If slot and drive are specified, only that drive is checked. Syntax: ONLINE [,S slot] [,D drive] Examples: Type "ONLINE" to display volume names for all drives. Or type "ONLINE,S6,D2" to display the volume name for slot 6, drive 2 only.

SEE Install only once: Type "-SEE" New command: SEE Function: Lets you view any program on a disk without loading it. SEE will print text (TXT) files as well as Applesoft program (BAS) files. Other file types may be dumped too, but not as effectively. Syntax: SEE pathname [,S slot] [,D drive] Comments: "pathname" is any filename. Press any key to pause a listing, followed by Esc to exit, or any other key to continue. Examples: Type "SEE/BIG.U/STARTUP" to display Big U's Applesoft (BAS) startup program. You can use SEE in a program (Esc to quit): 10 PRINT CHR$(4)"SEE PRODOS,S6,D1" PRODOS is a binary (SYS) file. Text (TXT) files look better, but there are none on the Big U disk.

SHOW Install only once: Type "-SHOW" New command: SHOW Function: Load a normal hi-res image from disk and/or reveal the hi-res screen without clearing it. For double hi-res, use SHOW.WIPE (next page). Syntax: SHOW [pathname] [,A page] [,F format] [,S slot] [,D drive] "pathname" is the name of a picture to see. "page" is a number: 1=page 1, 2=page 2 "format" is a number: 0=full graphics, 1=mixed graphics and text. If no format value is given, 0 is assumed. Examples: Run the file called "RANDY.BRANDT" to see a demo of how SHOW can be used. Type "SHOW,A1" to reveal all of hi-res page 1 without erasing it (works like HGR, but doesn't erase and doesn't include four text lines). Type "SHOW" to reveal the last screen accessed (full graphics, no text). Type "SHOW PIC,A2" to load a hi-res picture named "PIC" to page 2 and reveal it.

SHOW.WIPE (128k required) Install only once: Type "-SHOW.WIPE" New commands: SHOW and WIPE

SHOW (SHOW.WIPE command 1 of 2) Function: Loads a single or double hi-res image from disk and/or reveals the normal or double hi-res screen without clearing. SHOW works only with Beagle Graphics' two-file picture format. Syntax: Same as on previous page, except a third "page" parameter is allowed: 1=hi-res page 1, 2=hi-res page 2, 3=double hi-res. For double hi-res picture names, SHOW expects the second file to end in ".AUX". Examples: Type "SHOW DOUBLE,A3" to load the files "DOUBLE" and "DOUBLE.AUX" and display them as one double hi-res picture. Or simply type "SHOW,A3" to reveal the double hi-res screen.

WIPE (SHOW.WIPE command 2 of 2) Function: Reformats (erases) the ProDOS RAM disk. Syntax: WIPE [,A3] Comments: "WIPE" reformats /RAM. "WIPE,A3" does the same, but also saves hi-res page 1 in a /RAM file called "DHGR.AUX", thus protecting double hi-res graphics memory from being overwritten. It also protects future /RAM files from being overwritten by double hi-res graphics. Examples: Type "WIPE" to erase all /RAM files. Type "CAT/RAM" to see the blank directory. Load a normal hi-res picture to page 1. Now type "SHOW,A3" followed by "WIPE,A3".

XLISTER Install only once: Type "-XLISTER" New command: XLIST Function: Displays Applesoft programs in improved list format. Each statement is listed on a new line. For-Next loops are indented, and statements following IF'S are marked with a "*". See the sample printout on the next page. Syntax: XLIST [*] [line number or range] Specify single lines or ranges just like in Applesoft's LIST command. Because XLIST is a ProDOS command, it can be entered in lower case (and even be used from the monitor!). Type "XLIST*" to list to a printer in slot 1. With printer listings, you get page breaks and page numbers. If your program starts with a REM statement, that statement will appear as a header at the top of each page. If you're using ProDOS 1.1.1, XLISTER will automatically print the date and time in each header. Examples: Type "XLIST -100" to display lines 0-100 on the screen. Or type "XLIST* 10,20" to send lines 10 through 20 to your printer. In the example program below-You can type "RUN" to RUN it. You can type "RUN2' to SAVE it. You can type "RUN1" to XLIST it to printer. Each page of the printer listing will have line 0's REM printed on the top. To print only part of the program, add the line range to line 1. 0 GOTO 3: REM SAMPLE 1 PRINT CHR$(4);"XLIST*" : END 2 PRINT CHR$(4);"SAVE SAMPLE": END 3 REM PROGRAM STARTS HERE Sample Program XLISTing: 10 REM CUSTOM.LIST.DEMO 15 HGR

FOR PRINTER EXPERTS ONLY XLISTER contains eight printer enhancement bytes which may be used to turn on printer options such as compressed, bold, etc. Here's how to use them: 1. Type "BLOAD XLISTER". 2. Get out your printer manual and look up the hex codes for the desired printer options. 3. Type "CALL-151" to enter the monitor. 4. Type "4599:00 00 00 00 00 00 00 00", replacing the 00's with the proper codes. 5. Type "CALL 16384" to install the modified XLISTER, or type "BSAVE XLISTER" to make the changes permanent.

Big U's UTILITY Programs

BEEPERWORKS Requires Appleworks This program is for AppleWorks users only (versions 1.1 or 1.2). Even though we don't get paid to endorse AppleWorks, we'll let it be known that we use it for all of our word-processing needs. Its error beep, however, can get just a little annoying, especially when you make as many errors as we do. Thanks to BEEPERWORKS, your ears can at least get a little variety.

USING BEEPERWORKS 1. Type "-BEEPERWORKS" and a familiar screen will appear. Insert a working copy of your AppleWorks Startup disk (not the Program disk), and follow the instructions on the screen. If you can use AppleWorks, you can use this program. 2. Select option 2 from the main menu. The Beep Change Menu will be displayed, with values for the beep's pitch, duration and pause. Three sets of these values are shown; the current values, the boot-up values (stored on your disk), and AppleWorks' original values. 3. Do some experimenting, and pick the beep you like. We like the pitch at 20, the duration at 180, and the pause at 50. Pick your own beep. 4. When you're done, use the main menu save option to make your new beep a "permanent" part of AppleWorks. Hats off to AppleWorks for being unprotected!

BIGLINER BIGLINER is used to give your Applesoft programs "illegal" program lines numbered 65535. This prevents the average human from deleting or otherwise messing with those program lines, unless of course, he or she has a copy of BIGLINER! Line 65535 is commonly used to store Copyright notices in Rem statements. For some reason, Applesoft does not allow line numbers higher than 63999. Therefore, line 65535 cannot be deleted. No Goto's, Then's or Gosub's can access it either, but the program will work normally otherwise.

USING BIGLINER Load a backup copy of an Applesoft program and try the following steps: 1. Type "-BIGLINER". You will see a menu offering you four choices, followed by a listing of the highest legally-numbered line (if there is one). 2. Press "L" to list the entire Applesoft program. Pause with Control-S, or quit with Control-C. 3. Press "R" to raise the listed line number to number 65535. The highest legal line listed will be replaced. 4. Press "L" to list the program. The last line listed will now be 65535. 5. Press "C" to change the first line 65535 to 63000. If line 63000 is present in the program, the next available line number will be used. BIGLINER only changes the line numbers themselves; it doesn't check to see if the line is referenced by another statement. 6. To quit, press "Q".

CAT.DATER (ProDos 1.1.1 only) This is a small Applesoft program that makes the current ProDOS date and time appear following the directory name at the top of each catalog. If you don't have a clock/calendar in your Apple, use the DATE.SET program (page 63) to set the date first. USING CAT.DATER Type "-CAT.DATER". Then type "CAT" or "CATALOG" to see the date in your catalog. TECHNICAL NOTES: CAT.DATER is relocatable, so its address (variable AD in line 10) may be changed if you want to use page 3 of memory for other purposes. The existing setting allows it to be compatible with the CAT.FIXER (next page) and CAT.STEPPER (below).

CAT.STEPPER (ProDos 1.1.1 only) This program modifies the catalog routine so that you can "step" through a directory one or more files at a time. USING CAT.STEPPER Type "-CAT.STEPPER" to install the routine. Now your catalogs will pause every 19 files, about one screenful. Press the space bar to step one file at a time, or any other key to continue. Control-C exits the catalog, as usual. ADJUSTING CAT.STEPPER You may adjust the number of file names between pauses by Poking a number into location 838. For example, typing "POKE 838,5" would pause every 5 file names.

CAT.FIXER (ProDos 1.1.1 only) This program lets you enhance the functions of the "CATALOG" and "CAT" commands. The "Multiple File" options are handy for printer printouts of catalogs in multiple columns. USING CAT.FIXER Type "-CAT.FIXER" to get the program going. For reference, we have added letters A through G to the screen below:

                               CAT.FIXER CHOICES

CAT COMMAND CATALOG COMMAND —————— ———————- NORMAL CAT A NORMAL CATALOG SMART 40/80 B AUTO 80-COLUMN MULTIPLE FILES C AUTO 80-COLUMN MULTIPLE FILES D NORMAL CATALOG

          USE CURSOR KEYS AND RETURN FOR SELECT
                 OPTIONS FOR MULTIPLE FILES CAT

40-COLUMN SCREEN 80-COLUMN SCREEN —————- ——————– NORMAL CAT E TWO FILES/LINE TW0 FILES/LINE F FOUR FILES/LINE COMPLETE MESS G FIVE FILES/LINE

CAT/CATALOG OPTIONS (top half of screen): Use the arrow keys to move the flashing pointer to the set of options (A, B, C or D) that you want. (If your Apple can't display 80-columns, only options A and D are appropriate.): A: CAT acts normal. CATALOG acts normal. B: CAT acts like CATALOG if 80-columns visible. CATALOG auto-switches to 80-column screen. C: CAT makes multiple-columns. CATALOG auto-switches to 80-column screen. D: CAT makes multiple-columns. CATALOG acts normal. Press Return to select option A, B, C or D. If you select option A or B, skip to step 3. Selecting options C and D will move the pointer down to the bottom half of the screen. Press Esc to exit the program. 2. MULTIPLE-FILE OPTIONS (bottom half of screen): The options on the lower half of the screen apply to the CAT command only. Use the arrow keys to move the pointer to the set of options (E, F or G) that you want: E: 40-columns: normal CAT. 80-columns: 2 file names per line. F: 40-columns: 2 file names per line. 80-columns: 4 file names per line. G: 40-columns: Unreadable 80-columns: S file names per line. Press Return to select option E, F or G; or press Esc to go back to options A, B, C and D. 3. DEMO: Press "D" to test your new CAT or CATALOG display. Or press Esc to skip the demo. Press Esc once more to quit the program.

NORMALIZING CAT AND CATALOG CAT.FIXER alters ProDOS's Catalog function in memory. To get things back to normal, type "-CAT.FIXER" and select option A. Or reboot, or type "-BASIC.SYSTEM".

DATE.SET (ProDos 1.1.1 only) If you don't have a clock/calendar for your Apple, use this program to set the date and time which will appear next to your saved file names (instead of "<NO DATE>"). USING DATE.SET 1. Type "-DATE.SET" to load the program. 2. Type "CALL 20000" to run it. When you CALL 20000, the current date and time in memory will be displayed. If no valid date is present, the date stored in DATE.SET itself will appear. CHANGING THE VALUES Press the Left and Right Arrow keys to highlight the day, month, year, hours or minutes. Then press the Up and Down Arrows (or A and Z) to increase or decrease each one. (A "<NO DATE" option lies between December and January.) When you're satisfied, press Return. Or press Esc to exit with the original values restored. A DATE.SET BOOT-UP PROGRAM: Here is a sample time-set program that you could save under the name "STARTUP" so it will run each time you boot a particular disk:

10 D$=CHR$ (4): HOME: DS=20000: REM DS = DATE.SET ADDRESS 20 PRINT D$"-DATE.SET": CALL DS: REM GET DATE AND USER RESPONSE 30 IF PEEK(DS-1)<>0 THEN PRINT D$"BSAVE DATE.SET" 40 REM CONTINUE WITH PROGRAM

Line 30 in the program above saves DATE.SET with the new date if a change has occurred. With this program on your boot disk, the last boot date will always be given as the default value. In case you're interested, DATE.SET stores a zero in byte 19999 if the user exits with a date identical to the one stored in DATE.SET.

DISK.COPY.MORE DISK.COPY.MORE is a program which modifies Extra K's DISK.COPY program to work with 38-track (instead of normal 35track) disks (see pages 29 and 31). If you don't have Extra K, go buy it. We'll wait here.

USING DISK.COPY.MORE Type "-DISK.COPY.MORE" to run the program. When prompted, insert the Extra K disk and press Return. If you only have one 38 track drive, you must use a one-drive copy and do some disk swapping. To make things easier, put DISK.COPY.MORE and DISK.COPY on a 38-track disk along with a 304-block version of ProDOS (page 31). CHANGING DISK.COPY.MORE FOR 40 TRACKS If you have a special 40-track drive, here's how to upgrade DISK.COPY.MORE to work with it:

1. Type "BLOAD DISK.COPY.MORE". 2. Type "CALL -151". 3. Type "404A: 28" (Hex for 40). 4. Type "40A9: 34 30" (ASCII for 40). 5. Type "BSAVE DISK.COPY.MORE". If you want, you can look up your own hex and Ascii values for 39 or 8-track drives and plug them in.

ERROR.EDITOR Type "-ERROR.EDITOR" to change any of ProDOS's 19 error messages. The standard error messages will be displayed on the left half of the screen. The right side will show "-SAME-" if the message has not been changed.

CHANGING ERROR MESSAGES 1. Press "E" to begin editing. The center message will be highlighted by an inverse bar. 2. Use the arrow keys to move to the message you wish to change. Then press Return. 3. Type your new message. You may use letters of the alphabet (except J, Q & Z); and the characters "/", "(", ")", ".", and ":". Press Esc if you don't want to change the message, or press Return when you're done. 4. Select another message to edit if you want, or press Esc to leave edit mode. The words at the bottom of the screen tells you: LENGTH of your new message as you type it (20 characters maximum). AVAILABLE NIBBLES for your message. A nibble is half a byte. Some characters count as one nibble, and some count as two. A click will be heard whenever a two-nibble character is entered or deleted. Your message is limited to the available nibbles or 20 characters maximum. ALTERED is the number of messages changed so far. UPDATING BASIC.SYSTEM If you quit ERROR.EDITOR, your new error messages will be in effect until you reboot. (Test them with an illegal command or two.) If you want the new messages to be in effect every time you boot, you will need to update BASIC.SYSTEM on your boot-up disk:

1. Press "U" to update ProDOS's BASIC.SYSTEM file. You will be asked "UPDATE DISK IN DRIVE 1? (Y/D)". 2. Press "Y" to update BASIC.SYSTEM in the main directory of slot 6, drive 1. Or press "D" to toggle between drives 1 and 2. Press any other key to skip updating. Note: If you have renamed BASIC.SYSTEM, change the variable S$ in line 5.

RESTORING ORIGINAL ERROR MESSAGES Press "N" from the editor menu to normalize the messages in memory. Then press "U" to normalize the messages on disk. EXITING Leave the editor by pressing "Q" for Quit. Type "RUN" to restart the program with your altered error messages intact.

ABOUT TESTING ERROR MESSAGES To test ProDOS's "Syntax Error" messages, type something illegal like "CAT3". Typing something illegal like "COTALOG" will give you Applesoft's "?Syntax Error" message instead. You can't change this message, unless you buy a copy of our Beagle Basic disk. RAM.SAVE 128K required RAM.SAVE will copy all of your current RAM disk files onto a floppy disk in seconds, providing "permanent" storage for them. RAM.LOAD (next page) will load the files back into /RAM.

USING RAM.SAVE 1. Save a few files on /RAM in slot 3, drive 2. 2. Type "-RAM.SAVE". 3. Insert an erasable formatted disk into slot 6, drive 1 (or the drive you are set up for–see page 69). Warning: All previous files on the flopav will be erased. 4. Press Return. All of the /RAM files will be copied onto the floppy disk. Until you reformat it, this disk will not hold more than 119 blocks (about half of normal). 5. Catalog the floppy. It is now called "/RAM", and contains the same files as the original /RAM in slot 3, drive 2.

WHAT'S A RAM DISK ANYWAY? A phantom disk named "/RAM" lives in imaginary slot 3, drive 2 of 128K Apples with ProDOS. It has the advantage of letting you load and save files into memory at lightning speed. The problem is, RAM disk files disappear when the power goes off. The RAM disk works just like any disk, except it is fast and only holds 119 blocks-worth of files. To test your RAM disk: 1. Load a program. 2. Type "SAVE /RAM/FILENAME". 3. Type "CAT/RAM" or "CAT,S3,D2". 4. Or type "PREFIX/RAM" followed by "CAT". Get the picture? If not, you probably don't have 128K or you're not working with ProDOS.

RAM.LOAD RAM.LOAD loads files into /RAM from a floppy disk created by RAM.SAVE (previous page). USING RAM.LOAD 1. Type "-RAM.LOAD". 2. When prompted, insert your special floppy disk that was created with RAM.SAVE. Warning: use only special /RAM disks created by RAM.SAVE or semi-disaster will surely result! 3. Press Return to load all of the special floppy's files into /RAM. FLOPPY /RAM NOTE You may add to or delete files from the /RAM floppy as long as the floppy was created by RAM.SAVE.

RAM.SETUP This program lets you configure the RAM.SAVE and RAM.LOAD programs for the following two characteristics: I. The slot and drive that files will be copied to and from. 2. Whether or not you want the program to pause and prompt you to insert a disk. The pause option prompts you to insert the /RAM floppy and press Return before file copying begins. The no-pause option immediately begins reading and writing data. Use the nopause option only if RAM.LOAD will be used on the /RAM floppy. Then you can insert it, type "-RAM.LOAD" and everything else will be automatic. USING RAM.SETUP 1. Type "-RAM.SETUP". 2. Follow the instructions on the screen.

RENAMING TIP You may want to rename RAM.LOAD and RAM.SAVE to reflect the slot and drive selected. For example, RAM.SAVE.S6.D2 could be the version that works with drive 2. To do this, insert your own diskette before saving the configured program. After it's saved, type "RENAME RAM.SAVE, RAM.SAVE.S6.D2".

RENEW RENEW is a short routine for restoring Applesoft programs which have been zapped by a "NEW" command. Type "-RENEW immediately after "NEW" has been typed. If it works, hooray! If not, retype your program.

RUN.COUNTER This program will print the date your Applesoft program was last Run and the number of times it has ever been Run, each time it is Run. You need to append your program to ours. Here's how you do it: 1. Type "-APPENDER" (unless the APPENDER program is already in memory). 2. Type "LOAD RUN.COUNTER". 3. Type "&STORE" to hide the program. 4. Load the Applesoft program that you want to use with RUN.COUNTER. 5. Make sure your program has no program lines numbered lower than 9. 6. Type "&RECALL" to append the two programs. 7. Change the value of P$ in line 1 to the name of your program. For example: 1 P$="MY.FILE" 8. Re-save your program using the name in line 1. Your program is now ready to use. Every time it is Run, the program name will be printed on the screen with the Run number and last used date. After you enter today's date, the Rem in line zero will be updated and the program will be re-saved under the name defined by P$. To prevent the Run number from printing, delete program line 4. To prevent the date from printing, delete line 5.

SAVE.40 and SAVE.80 These programs let you save 40-and 80-column text screens on disk. You may view the saved screens by typing a hyphen followed by the name of the saved screen. 80column files are compatible with those created by CRT.WRITER.

USING SAVE.40 I. Bload SAVE.40 2. CALL 20134 USING SAVE.80 I. Bload SAVE.80 2. CALL 20010 After the CALL, the screen will be copied to a buffer on hi-res page 2, and you will be asked for a file name (a legal ProDOS pathname, which may include slot and drive). The screen will then be saved. To prevent your typed message from being saved, you should always save screens from within your programs. For example:

10 PRINT CHR$(4)"BLOAD SAVE.80" 20 FOR I=1 TO 20: PRINT "STUFF ALL OVER THE 80-COLUMN SCREEN.": NEXT 30 CALL 20010 : REM SAVE SCREEN 40 REM CONTINUE WITH PROGRAM

Now that you've saved a screen or two, type "HOME" and then "-filename" (substitute your saved screen's name for "filename"). Loading an 80-column screen automatically switches to 80-column display. Try this miniexample: 1 PRINT CHR$(4)"-FILE.NAME" : REM USE THE APPROPRIATE FILENAME 2 HOME : GET X$ : CALL 20366 : REM USE CALL 20416 FOR 40-COLUMNS 3 GET X$ : GOTO 2 : REM PRESS CONTROL-RESET WHEN YOU GET BORED The CALL in line 2 keeps recopying the screen from its buffer.

PRODOS COMMAND SUMMARY (Deleted. See other references for this information)

MEMORY USAGE Most of the BIG U AMPER and COMMAND programs take away some programming memory by moving HIMEM down and installing themselves above the ProDOS buffers. The following list shows how much memory is used by each program: One-pagers (256 bytes): APPENDER, DUMP.40, DUMP.80, EST, ONLINE and SUPER.POKE.
