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.
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
REMOTE Job Entry Protocol (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.

REMOTE Job Entry Protocol (Oct. 16, 1972) RFC 407 NIC 12112 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
REMOTE Job Entry Protocol (Oct. 16, 1972) RFC 407 NIC 12112 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.).
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>
<integer>::= D<decimal-integer> | O<octal-integer> | H<hexadecimal-integer> <host-file>::= <host><attributes>/<pathname> <attributes>::= <empty> | :<transmission><code> <transmission>::= <empty> | T | A | N <empty> implies default which is N for Input files and A for Output files 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.
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.
8
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>
9
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.
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).
10
REMOTE Job Entry Protocol (Oct. 16, 1972) RFC 407 NIC 12112 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.
12
REMOTE Job Entry 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.
13
REMOTE Job Entry Protocol (Oct. 16, 1972) RFC 407 NIC 12112 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.
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.
15
REMOTE Job Entry Protocol (Oct. 16, 1972) RFC 407 NIC 12112 The assigned reply codes relating to RJE are:
000 General information message (time of day, etc.) 030 Server availability information 050 FTP commentary or user information 060 RJE or Batch system commentary or information 100 System status reply 150 File status reply 151 Directory listing reply 160 RJE system general status reply 161 RJE job status reply 200 Last command received ok 201 An ABORT has terminated activity, as requested 202 ABORT request ignored, no activity in progress 203 The requested Transmission Control has taken effect 204 A REINIT command has been executed, as requested 230 Log-on completed 231 Log-off completed, goodbye. 232 Log-off noted, will complete when transfer done 240 File transfer has started 250 FTP File transfer started ok 251 FTP Restart-marker-reply Text is: MARK yyyy = mmmm where yyyy is data stream marker value (yours) and mmmm is receiver's equivalent mark (mine) 252 FTP transfer completed ok 253 Rename completed 254 Delete completed 260 Job <job-id> accepted for processing 261 Job <job-id> completed, awaiting output transfer 262 Job <job-id> Cancelled as requested 263 Job <job-id> Altered as requested to state <status> 264 Job <job-id>,<job-file-id> transmission in progress 300 Connection greeting message, awaiting input 301 Current command not completed (may be sent after suitable delay, if not "crlf") 330 Enter password (may be sent with hide-your-input mode) 360 INPUT has never specified an INPATH 400 This service is not implemented 401 This service is not accepting log-on now, goodbye. 430 Log-on time or tries exceeded, goodbye. 431 Log-on unsuccessful, user and/or password invalid 432 User not valid for this service 434 Log-out forced by operator action, please phone site 435 Log-out forced by system problem 436 Service shutting down, goodbye 440 RJE could not log-on to remote FTP for input transfer 441 RJE could not access the specified input file thru FTP 442 RJE could not establish <host-socket> input connection

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.
REINIT 204 467,500-505 USER 230,330 430-432,500-505 PASS 230 430-432,500-505 BYE 231,232 500-505 INID 200 500-505 INPASS 200 500-505 INPATH 200 500-505 INPUT 240 360,440-442,500-505 sec. input retrieval 260 460,461 sec. job execution 261 462,463 sec. output transmission - 443-445,466 ABORT (input) 201,202 500-505 OUTUSER 200 500-505 OUTPASS 200 500-505 OUT 200 500-505 CHANGE 200 500-505 RESTART/RECOVER/BACK /SKIP/ABORT (output)/HOLD 203 464,500-506 STATUS 1xx,264 460-465,500-505 CANCEL 262 464,500-506 ALTER 263 464,465,500-506 OP 200 500-505 Spontaneous 0xx,300,301 434-436
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).

REMOTE Job Entry Protocol (Oct. 16, 1972) RFC 407 NIC 12112 HOSTA USER RUNS JOB AT HOSTC, INPUT FROM HOSTB
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.
