                     REMOTE JOB ENTRY PROTOCOL

INTRODUCTION

 Remote job entry is the mechanism whereby a user at one location
 causes a batch-processing job to be run at some other location.  This
 protocol specifies the Network standard procedures for such a user to
 communicate over the Network with a remote batch-processing server,
 causing that server to retrieve a job-input file, process the job,
 and deliver the job's output file(s) to a remote location.  The
 protocol uses a TELNET connection (to a special standardized logger,
 not socket 1) for all control communication between the user and the
 server RJE processes.  The server-site then uses the File Transfer
 Protocol to retrieve the job-input file and to deliver the output
 file(s).
 There are two types of users:  direct users (persons) and user
 processes.  The direct user communicates from an interactive terminal
 attached to a TIP or any host.  This user may cause the input and/or
 output to be retrieved/sent on a specific socket at the specified
 host (such as for card readers or printers on a TIP), or the user may
 have the files transferred by file-id using File Transfer Protocol.
 The other type of user is a RJE User-process in one remote host
 communicating with the RJE Server-process in another host.  This type
 of user ultimately receives its instructions from a human user, but
 through some unspecified indirect means.  The command and response
 streams of this protocol are designed to be readily used and
 interpreted by both the human user and the user process.
 A particular user site may choose to establish the TELNET control
 connection for each logical job or may leave the control connection
 open for extended periods.  If the control connection is left open,
 then multiple job-files may be directed to be retrieved or optionally
 (to servers that are able to determine the end of one logical job by
 the input stream and form several jobs out of one input file) one
 continuous retrieval may be done (as from a TIP card reader).  This
 then forms a "hot" card reader to a particular server with the TELNET
 connection serving as a "job monitor".  Since the output is always
 transferred job at a time per connection to the output socket, the
 output from this "hot" reader would appear when ready as if to a
 "hot" printer.  Another possibility for more complex hosts is to
 attach an RJE User-process to a card reader and take instructions
 from a lead control card, causing an RJE control TELNET to be opened
 to the appropriate host with appropriate log-on and input retrieval
 commands.  This card reader would appear to the human user as a
 Network "hot" card reader.  The details of this RJE User-process are
 beyond the scope of this protocol.

GENERAL SPECIFICATIONS

 User
    A human user at a real terminal or a process that supplies the
    command control stream causing a job to be submitted remotely will
    be termed the User.  The procedure by which a process user
    receives its instructions is beyond the scope of this protocol.
 User TELNET
    The User communicates its commands over the Network in Network
    Virtual Terminal code through a User TELNET process in the User's
    Host.  This User TELNET process initiates its activity via ICP to
    the standard "RJE Logger" socket (socket 5) at the desired
    RJE-server Host.
 RJE-Server TELNET
    The RJE-server process receives its command stream from and sends
    its response stream to the TELNET channel through an RJE-server
    TELNET process in the server host.  This process must listen for
    the ICP on the "RJE Logger" socket (and cause appropriate ICP
    socket shifting).
 TELNET Connection
    The command and response streams for the RJE mechanism are via a
    TELNET-like connection to a special socket with full
    specifications according to the current NWG TELNET protocol.
 RJE-Server
    The RJE-Server process resides in the Host which is providing
    Remote Batch Job Entry service.  This process receives input from
    the RJE-server TELNET, controls access through the "log-on"
    procedure, retrieves input job files, queues jobs for execution by
    the batch system, responds to status inquiries, and transmits job
    output files when available.
 User FTP
    All input and output files are transferred under control of the
    RJE-server process at its initiative.  These files may be directly
    transferred via Request-for-connection to a specific Host/socket
    or they may be transferred via File Transfer Protocol.  If the
    latter method is used, then the RJE-server acts through its local
    User FTP process to cause the transfer.  This process initiates
                                 2

                                                       (Oct. 16, 1972)
                                                     RFC 407 NIC 12112
                                                                      
                                                                      
    activity by an active Request-for-connection to the "FTP Logger"
    in the foreign host.
 Server FTP
    This process in a remote host (remote from the RJE-server) listens
    for an ICP from the User FTP and then acts upon the commands from
    the User FTP causing the appropriate file transfer.
 FTP
    When File Transfer Protocol is used for RJE files, the standard
    FTP mechanism is used as fully specified by the current NWG
    FTProtocol.
 RJE Command Language
    The RJE system is controlled by a command stream from the User
    over the TELNET connection specifying the user's identity
    (log-on), the source of the job input file, the disposition of the
    job's output files, enquiring about job status, altering job
    status or output disposition.  Additional commands affecting
    output disposition are includable in the job input file.  This
    command language is explicitly specified in a following section of
    this protocol.
 RJE Command Replies
    Every command input from the User via TELNET calls for a response
    message from the RJE-server to the User over the TELNET
    connection.  Certain other conditions also require a response
    message.  These messages are formatted in a standardized manner to
    facilitate interpretation by both human Users and User processes.
    A following section of this protocol specifies the response
    messages.

RJE COMMANDS OVER TELNET CONNECTION

 GENERAL CONVENTIONS
 1. Each of the commands will be contained in one input line
    terminated by the standard TELNET "crlf".  The line may be of any
    length desired by the user (explicitly, not restricted to a
    physical terminal line width).  The characters "cr" and "lf" will
    be ignored by the RJE-server except in the explicit order "crlf"
    and may be used as needed for local terminal control.
 2. All commands will begin with a recognized command name and may
    then contain recognized syntactic element strings and free-form
    variable strings (for user-id, file-ids, etc.).  Recognized words
    consist of alphanumeric strings (letters and digits) or
    punctuation.  Recognized alphanumeric string elements must be
    separated from each other and from unrecognizable strings by at
    least one blank or a syntacticly permitted punctuation.  Other
    blanks may be used freely as desired before or after any syntactic
    element ("blank" is understood here to mean ASCII SPACE (octal
    040); formally:  <blank>::= <blank><ASCII SPACE> | <ASCII SPACE> ;
    thus, a sequence of SPACES is also permissible in place of
    <blank>, although there is no syntactic necessity for there to be
    more than one).  The "=" after the command name in all commands
    except OUT and CHANGE is optional.
 3. Recognized alphanumeric strings may contain upper case letters or
    lower case letters in any mixture without syntactic
    differentiation.  Unrecognizable strings will be used exactly as
    presented with full differentiation of upper and lower case input,
    unless the host finally using the string defines otherwise.
 4. There are two types of Unrecognizable strings:  final and
    imbedded.  Final strings appear as the last syntactic element of a
    command and are parsed as beginning with the next non-blank
    character of the input stream and continuing to the last non-blank
    character before the "crlf".
 Imbedded strings include "job-id" and "job-file-id" in the OUT,
 CHANGE, and ALTER commands.  At present these fields will be left
 undelimited since they must only be recognizable by the server host
 which hopefully can recognize its own job-ids and file-names.
 SYNTAX
 The following command descriptions are given in a BNF syntax.  Names
 within angle brackets are non-terminal syntactic elements which are
 expanded in succeeding syntactic equations.  Each equation has the
                                 4

 defined name on the left of the ::= and a set of alternative
 definitions, separated by vertical lines "|", on the right.
 REINITIALIZE
    REINIT
       This command puts the user into a state identical to the state
       immediately after a successful connection to the RJE-server,
       prior to having sent any commands over the TELNET connection.
       The effective action taken is that of an ABORT and a flushing
       of all INPUT, OUTPUT and ID information.  Naturally, the user
       is still responsible for any usage charges incurred prior to
       his REINIT command.  The TELNET connection is not affected in
       any way.
 USER
    User = <user-id>
       This command must be the first command over a new TELNET
       connection.  As such, it initiates a "logon" sequence.  The
       response to this command is one of the following:
          1.  User code in error.
          2.  Enter password (if user code ok).
          3.  Log-on ok, proceed (if no password requested).
       Another USER command may be sent by the User at any time to
       change Users.  Further input will then be charged to the new
       user.  A server may refuse to honor a new user command if it is
       not able to process it in its current state (during input file
       transfer, for example), but the protocol permits the USER
       command at any time without altering previous activity.  An
       incorrect subsequent USER command or its following PASS command
       are to be ignored with error response, leaving the original
       User logged-in.
       It is permissable for a server to close the TELNET connection
       if the initial USER/PASS commands are not completed within a
       server specified time period.  It is not required or implied
       that the "logged-on" User's user-id be the one used for file
       transfer or job execution, but only identifies the submitter of
       the command stream.  Servers will establish their own rules
       relating user-id with the job-execution-user for Job or Output
       alteration commands.
       Successful "log-on" always clears any previous Input or Output
       default parameters (INID, etc.).

 PASS
    Pass = <password>
       This command immediately follows a USER command and completes
       the "log-on" procedure.  Although a particular Server may not
       require a password and has already indicated "log-on ok" after
       the USER command, every Server must permit a PASS command (and
       possibly ignore it) and acknowledge it with a "log-on ok" if
       the log-on is completed.
 BYE
    BYE
       This command terminates a USER and requests the RJE server to
       close the TELNET connection.  If input transfer is not in
       progress, the TELNET connection may be closed immediately; if
       input is in progress, the connection should remain open for
       result response and then be closed.  During the interim, a new
       USER command (and no other command) is acceptable.
       An unexpected close on the TELNET connection will cause the
       server to take the effective action of an ABORT and a BYE.
 INID/INPASS
    INID = <user-id>
    INPASS = <password>
       The specified user-id and password will be sent in the File
       Transfer request to retrieve the input file.  These parameters
       are not used by the Server in any other way.  If this command
       does not appear, then the USER/PASS parameters are used.
 INPATH/INPUT
    INPATH = <file-id>
    INPUT = <file-id>
    INPUT
       NOTE:  The following syntax will be used for output as well.
          <file-id>::= <host-socket> | <host-file>
          <host-socket>::= <host>,<socket><attributes> |
                           <socket><attributes>
             no <host> part implies the User-site host
          <host>::= <integer>

                        marks but without other carriage-control

                        carriage-control

          <code>::= <empty> | E
                <empty> specifies NVT ASCII code
                E specifies EBCDIC
          <pathname>::= <any string recognized by the FTP Server at
                        the site of the file>
       The <file-id> syntax is the general RJE mechanism for
       specifying a particular file source or destination for input or
       output.  If the <host-socket> form is used then direct transfer
       will be made by the RJE-Server to the named socket using the
       specified <attributes>.  If the <host-file> form is used then
       the RJE-server will call upon its local FTP-user process to do
       the actual transfer.  The data stream in this mode is either
       TELNET-like ASCII or blocked records (which may use column 1
       for ASA carriage-control).  Although A mode is permitted on
       input (column 1 is deleted) the usual mode is the default N.
       The output supplies carriage-control in the first character of
       each record ("blank" = single-space, "1" = new-page, etc.),
       while the optional N mode transfers the data only (as to a card
       punch, etc.).
       The <pathname> is an arbitrary Unrecognized string which is
       saved by RJE-server and sent back over FTP to the FTP-server to
       retrieve or store the appropriate files.
       INPATH or INPUT commands first store the specified <file-id> if
       one is supplied, and then the INPUT command initiates input.
       The INPATH name may be used to specify a file-id for later
       input and the INPUT command without file-id will cause input to
       initiate over a previously specified file-id.  An INPUT "crlf"
       command with no previous <file-id> specified is illegal.

 ABORT
    ABORT
       This command aborts any input retrieval in progress, discards
       already received records, and closes the retrieval connection.
       Note:  ABORT with parameters is an Output Transmission control
       (see below).
 OUTUSER/OUTPASS
    OUTUSER = <user-id>
    OUTPASS = <password>
       The specified user-id and password will be sent in the File
       Transfer request to send the output file(s).  These parameters
       are not used by the Server in any other way.  If this command
       does not appear, then the USER/PASS parameters are used.
 OUT
    OUT <out-file> = <disp>
       <out-file>::= <empty> | <job-file-id>
             <empty> implies the primary print file of the job
       <job-file-id>::= <string representing a specific output file
                        from the job as recognized by the Server>
       <disp>::= <empty><file-id> | (H) | (S)<file-id>|(D)
             <empty> specifies Transmit then discard
             (H) specifies Hold-only, do not transmit
             (S) specifies Transmit and Save
             (D) specifies discard without transmitting
       Note:  Parentheses are part of the above elements.
       <file-id>::= (same as for INPUT command)
       This command specifies the disposition of output file(s)
       produced by the job.  Unspecified files will be Hold-only by
       default.  The OUTUSER, OUTPASS, and OUT commands must be
       specified before the INPUT command to be effective.  These
       commands will affect any following jobs submitted by this USER
       over this RJE-TELNET connection.  A particular job may override
       these commands by NET control cards on the front of the input
       file.
       Once output disposition is specified by this OUT command or by
       a NET OUT card, the information is kept with the job until
       final output disposition, and is modifiable by the CHANGE
       command.

                                                     RFC 407 NIC 12112
                                                                      
                                                                      
       On occasion, the server may find that the destination for the
       output is "busy" (i.e., RFC to either Server-FTP or specified
       socket is refused), or that the host which should receive the
       output is dead.  In these cases, the server should wait several
       minutes and then try to transmit again.
 OUTPUT RE-ROUTE
    CHANGE <job-id><blank><out-file> = <disp>
       This command changes the output disposition supplied with the
       job at submission.  The <job-id> is assumed recognizable by the
       RJE-server, who may verify if this USER is authorized to modify
       the specified job.  After the job is identified, the other
       information has the same syntax and semantics as the original
       OUT command.  CHANGE command may be specified for a job-file-id
       which was not mentioned at submission time and has the same
       effect as an original OUT command.
 OUTPUT CONTROLS DURING TRANSMISSION
    <command><blank><count><blank><what>
    <command>::= RESTART | RECOVER | BACK | SKIP |
    ABORT | HOLD
    These commands specify (respectively):
       Restart the transmission (new RFC, etc.)
       Recover restarts transmission from last FTP
       Restart-marker-reply
       (see FTP).
       Back up the output "count" blocks
       Skip the output forward "count" blocks
       Abort the output, discarding it
       Abort the output, but Hold it
    <count>::= <empty> | <integer>
       <empty> implies 1 where defined
    <what>::= @<file-id> | <job-id><job-file-id>
    <disp>::= (same as for OUT command)
    <file-id>::= (same as for INPUT command)
    <integer>::= (same as for INPUT command)
    <job-id>::= <server recognized job identifier which was supplied
                at INP completion by the server>
    <job-file-id>::= <server recognized file identifier or if missing
                     then the prime printer output of the specified
                     job>

    This collection of commands will modify the transmission of output
    in progress or recently aborted.  If output transmission is
    cut-off before completion, then the RJE-server will either try to
    resend the entire file if the file's <disp> was
    Transmit-and-discard or will Hold the file for further User
    control if the <disp> was (S) transmit-and-Save.  Either during
    transmission, during the Save part of a transmit-and-Save, or for
    a Hold-only file, the above commands may be used to control the
    transmission.  The @<file-id> form of <what> is permitted only if
    transmission is actually in progress.
    If the file's state is inconsistent with the command, then the
    command is illegal and ignored with reply.
 STATUS
    STATUS <job-id>
    STATUS <job-id><blank><job-file-id>
       These commands request the status of the RJE-server, a
       particular job, or the transmission of an output or input file,
       respectively.  The information content of the Status reply is
       site dependent.
 CANCEL/ALTER
    CANCEL <job-id>
    ALTER <job-id><blank><site dependent options>
       These commands change the course of a submitted job.  CANCEL
       specifies that the job is to be immediately terminated and any
       output discarded.  ALTER provides for system dependent options
       such as changing job priority, process limits, Teminate without
       Cancel, etc.
 OP
    OP (any string)
       The specified string is to be displayed to the Server site
       operator when any following job is initiated from the batch
       queue of the Server.  This command usually appears in the input
       file as a NET OP control card, but may be a TELNET command.  It
       is cancelled as an all-jobs command by an OP "crlf" command (no
       text supplied).

RJE CONTROL CARDS IN THE INPUT FILE

 Certain RJE commands may be specified by control cards in the front
 of the input file.  If these controls appear, they take precedence
 over the same command given thru the RJE-TELNET connection and affect
 only this specific job.  All these RJE control cards must appear as
 the first records of the job's input-file.  They all contain the
 control word NET in columns 1 through 3.  Scanning for these controls
 stops when the first card without NET in col 1-3 is encountered.
 The control commands appear in individual records and are terminated
 by the end-of-record (usually an 80 column card-image).  Continuation
 is permitted onto the next record by the appearance of NET+ in
 columns 1-4 of the next record.  Column 5 of the next record
 immediately follows the last character of the previous record.
    NET OUTUSER = <user-id>
    NET OUTPASS = <password>
    NET OUT <out-file> = <disp>
    NET OP <any string>
 See the corresponding TELNET command for details.  One option
 permitted by the NET OUTUSER and NET OUT controls not possible from
 the TELNET connection is specification of different OUTUSERs for
 different OUTS, since the TELNET stored and supplies only an initial
 OUTUSER, but the controls may change OUTUSERs before each OUT control
 is encountered.

RJE USE OF FILE TRANSFER PROTOCOL

 Most non-TIP files will be transferred to or from the RJE-server
 through the FTP process.  RJE-server will call upon its local
 FTP-user supplying the Host, File-pathname, User-id, Password, and
 Mode of the desired transfer.  FTP-user will then connect to its
 FTP-server counterpart in the specified host and set up a transfer
 path.  Data will then flow through the RJE-FTP interface in the
 Server, over the Network, from/to the foreign FTP-server and then
 from/to the specified File-pathname in the foreign host's file
 storage space.  On output files, the file-pathname may be recognized
 by the foreign host as directions to a printer or the file may simply
 be stored; a User-RJE-process can supply an output <file-id> by
 default which is recognized by its own Server-FTP as routing to a
 printer.
 Although many specifics of the RJE-Server/User-FTP interface are
 going to be site dependent, there are several FTP options which will
 be used in a standard way by RJE-Servers:
                                 11
                                             REMOTE Job Entry Protocol
                                                       (Oct. 16, 1972)
                                                     RFC 407 NIC 12112
                                                                      
                                                                      
    1. A new FTP connection will be initiated for each file to be
       transferred.  The connection will be opened with the RJE User
       supplied User-id (OUTUSER or INUSER) and Password.
    2. The data bytesize will be 8 bits.
    3. The FTP Type, Structure, and Mode parameters are determined by
       the RJE transfer direction (I/O), and the <transmission> and
       <code> options supplied by the User:
   I/O   <TRANS>   <CODE>   FTP-TYPE   FTP-STRUCTURE   FTP-MODE
    I*      N        -         A             R            B
    I       N        E         E             R            B
    I       T        -         A             F            S
    I       T        E         E             F            S
    I       A        -         P             R            B
    I       A        E         F             R            B
 
    O*      A        -         P             R            B
    O       A        E         F             R            B
    O       N        -         A             R            B
    O       N        E         E             R            B
    O       T        -         A             F            S
    O       T        E         E             F            S
 
            (*indicates default)
    4. The service commands used will be Retrieve for input and Append
       (with create) for output.  The FTP pathname will be the
       <pathname> supplied by the RJE User.
    5. On output in B form, the User-FTP at the RJE-Server site will
       send Restart-markers at periodic intervals (like every 100
       lines, or so), and will remember the latest
       Restart-marker-reply with the file.  If the file transfer is
       not completed and the <disp> is (S) then the file will be held
       pending User intervention.  The User may then use the RECOVER
       command to cause a FTP restart at the last remembered
       Restart-marker-reply.
    6. The FTP Abort command will be used for the RJE ABORT and CANCEL
       commands.
    7. For transfers where the FTP-MODE is defined as B, the user FTP
       may optionally attempt to use H mode.
 The specific form of the FTP commands used by an RJE-Server site, and
 the order in which they are used will not be specified in this
 protocol.

                                                       (Oct. 16, 1972)
                                                     RFC 407 NIC 12112
                                                                      
                                                                      
 Errors encountered by FTP fall into three categories:  a) access
 errors or no storage space error; b) command format errors; and c)
 transfer failure errors.  Since the commands are created by the
 RJE-Server process, an error is a programming problem and should be
 logged for attention and the situation handled as safely as possible.
 Transmission failure or access failure on input cause an effective
 ABORT and user notification.  Transmission failure on output causes
 RESTART or Save depending on <disp> (see OUT command).  Access
 failure on output is a problem since the User may not be accessible.
 A status response should be queued for him, should he happen to
 inquire; a <disp> = (S) file should be Held; and a <disp> = <empty>
 transmit-and-discard file should be temporarily held and then
 discarded if not claimed.  "Temporarily" is understood here to mean
 at least several days, since particularly in the case of jobs which
 generate voluminous output at great expense to the User, he should be
 given every chance to retrieve his rightful output.  Servers may
 elect, however, to charge the User for the file-storage space
 occupied by the held output.

REPLIES OVER THE TELNET CONNECTION

 Each action of the RJE-server, including entry of each TELNET
 command, is noted over the TELNET connection to the User.  These
 RJE-server replies are formatted for Human or Process interpretation.
 They consist of a leading 3-digit numeric code followed by a blank
 followed by a text explanation of the message.  The numeric codes are
 assigned by groups for future expansion to hopefully cover other
 protocols besides RJE (like FTP).  The numeric code is designed for
 ease of interpretation by processes.  The three digits of the code
 are interpreted as follows:
 The first digit specified the "type" of response indicated:
    000
       These "replies" are purely informative, and are issued
       voluntarily by the Server to inform a User of some state of the
       server's system.
    100
       Replies to a specific status inquiry.  These replies serve as
       both information and as acknowledgment of the status request.
    200
       Positive acknowledgment of some previous command/request.  The
       reply 200 is a generalized "ok" for commands which require no
       other comment.  Other 2xx replies are specified for specific
       successful actions.
    300
       Incomplete information supplied so far.  No major problem, but
       activity cannot proceed with the input specified.
    400
       Unsuccessful reply.  A request was correctly specified, but
       could not be correctly completed.  Further attempts will
       require User commands.
    500
       Incorrect or illegal command.  The command or its parameters
       were invalid or incomplete from a syntactic view, or the
       command is inconsistent with a previous command.  The command
       in question has been totally ignored.

    600-900
       Reserved for expansion
 The second digit specifies the general subject to which the response
 refers:
    x00-x29
       General purpose replies, not assignable to other subjects.
    x30
       Primary access.  These replies refer to the attempt to "log-on"
       to a Server service (RJE, FTP, etc.).
    x40
       Secondary access.  The primary Server is commenting on its
       ability to access a secondary service (RJE must log-on to a
       remote FTP service).
    x50
       FTP results.
    x60
       RJE results.
    x70-x99
       Reserved for expansion.
 The final digit specifies a particular message type.  Since the code
 is designed for an automaton process to interpret, it is not
 necessary for every variation of a reply to have a unique number,
 only that the basic meaning have a unique number.  The text of a
 reply can explain the specific reason for the reply to a human User.
 Each TELNET line (ended by "crlf") from the Server is intended to be
 a complete reply message.  If it is necessary to continue the text of
 a reply onto following lines, then those continuation replies contain
 the special reply code of three blanks.

SEQUENCING OF COMMANDS AND REPLIES

 The communication between the User and Server is intended to be an
 alternating dialogue.  As such, the User issues an RJE command and
 the Server responds with a prompt primary reply.  The User should
 wait for this initial success or failure response before sending
 further commands.
 A second type of reply is sent by Server asynchronously with respect
 to User commands.  These replies report on the progress of a job
 submission caused by the INPUT command and as such are secondary
 replies to that command.
 The final class of Server "replies" are strictly informational and
 may arrive at any time.  These "replies" are listed below as
 spontaneous.

 Note:  For commands appearing on cards, a separate set of error codes
 is provided (507-512).  Since these error replies are
 "asynchronously" sent, and thus could cause some confusion if the
 user is in the process of submitting a new job after the present one,
 the error replies must identify which job has the faulty card(s).

 TYPICAL RJE SCENARIOS
    TIP USER WANTING HOT CARD READER TO HOSTX
       1. TIP user opens TELNET connection to HOSTX socket 5
       2. Commands sent over TELNET to RJE
          USER=myself
          PASS=dorwssap
          OUT=H70002
          INPUT=H50003
       3. RJE-server connects to the TIP's device 5 and begins
          reading.  When end-of-job card is recognized, the job is
          queued to run.  The connection to the card reader is still
          open for more input as another job.
       4. The first job finishes.  A connection to the TIP's device 7
          is established by RJE-server and the output is sent as an
          NVT stream.
       5. Continue at any time with another deck at step 3.
    TIP WITH JOB-AT-A-TIME CARD READER
       1. thru 4) the same but User closes Reader after the deck
       2. The output finishes and the printer connection closes.
       3. INPUT may be typed any time after step 3 finishes and
          another job will be entered starting at 3.

    HOSTA USER RUNS JOB AT HOSTC, INPUT FROM HOSTB
       1. User TELNET connects to HOSTC socket 5 for RJE
          USER=roundabout
          PASS=aaabbbc
          OUTUSER=roundab1
          OUT=:E/.sysprinter
          OUT puncher = (S)HOSTB:NE/my.savepunch
          INUSER=rounder
          INPASS=x.x.x
          INPUT=HOSTB:E/my.jobinput
       2. The RJE-server has FTP retrieve the input from HOSTB using
          User-id of "rounder" and Password of "x.x.x" for file named
          "my.jobinput".
       3. The job finishes.  RJE-server uses FTP to send two files:
          the print output is sent to HOSTA in EBCDIC with ASA
          carriage control to file ".sysprinter" while the file known
          as "puncher" is sent to HOSTB in EBCDIC without
          carriage-control to file "my.savepunch".
       4. when the outputs finish, RJE-server at HOSTC discards the
          print file but retains the "puncher" file.
       5. The User who has signed out after job submission has gotten
          his output and checked his file "my.savepunch" at HOSTB.  He
          deletes the saved copy at HOSTC by re-calling RJE at HOSTC.
          USER=roundabout
          PASS=aaabbbcc
          ABORT job 123 puncher
                 or
          CHANGE job 123 puncher = (D)
