         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.).

                                               REMOTE Job Entry Protocol
                                                         (Oct. 16, 1972)
                                                       RFC 407 NIC 12112
                                                                        
                                                                        
   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>
            <socket>::= <integer>

                  T       specifies TELNET-like coding with embedded
                          "crlf" for new-line, "ff" for new-page
                  N       specifies FTP blocked transfer with record
                          marks but without other carriage-control
                  A       specifies FTP blocked records with ASA
                          carriage-control
                          (column 1 of image is forms 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.

                                                       RFC 407 NIC 12112
                                                                        
                                                                        
   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.

                                               REMOTE Job Entry Protocol
                                                         (Oct. 16, 1972)
                                                       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>

                                               REMOTE Job Entry Protocol
                                                         (Oct. 16, 1972)
                                                       RFC 407 NIC 12112
                                                                        
                                                                        
      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.
