Introduction
This RFCis the follow-on document to RFC#436, which briefly
described UCSB'S RJS. This document restates the essence of the
official RJE protocol (RFC#407), and documents in detail UCSB's
implementation of it.
The program described here is available under socket 5 at UCSB, and
supports a subset of the official protocol. Specifically, no checks
are made for RJE control cards in the input file, jobs may not be
batched in the input file, only output file dispositions of discard
and transmit-and-discard are implemented, no restart markers are sent
on output in FTP blocked mode, and several of the commands are not
implemented. There are also other ways in which RJS is known to be
less than ideal. For example, whenever any error is detected while
processing a job, such as the output's destination host being dead,
the job is abandoned, and any further output deleted. A re-write of
RJS is scheduled for the near future (in about six months), and many
of these deficiencies will be corrected at that time. (Any
suggestions for further improvements are more than welcome, and may
be made through the Journal to MCK, by mail to the author at the UCSB
Computer Center, or by telephone at (8O5) 961-3454.)
In addition to the deviations from the protocol stated above, several
modifications have been made to increase user convience.
Specifically, the INACCT, OUTACCT, and ACCT commands have been added
to accommodate users of TENEX and other systems requiring an account
number, OUTPATH has been added as a synonym for OUT and INUSER for
INID, and the BYE command does not cause an ABORT. Also, in
recognition of the fact that the official protocol is biased heavily
toward use by programs, and is therefore rather cumbersome for human
users, an alternate, optional, command syntax has been provided. An
attempt was made to make this alternate syntax, called 'local
syntax', as 'natural' as possible to a human user. It also provides
some features not available with the standard syntax.
Service Provided
The UCSB Computer Center operates an IBM 360/75 and runs OS MVT
release 21.0 and HASP. All batch jobs at UCSB enter the system
through HASP, and therefore RJS acts as an interface between the user
and HASP. RJS's function is to provide the user with a HASP virtual
RJE terminal, consisting of card reader, card punch, line printer and
operator's console, and to manage the first three of these for the
user in response to commands issued by him. By virtue of the fact
that RJS maintains the correspondence between a particular user and
the HASP RJE terminal owned by him, the user may issue commands to
alter the status of those jobs submitted by him through his RJE
terminal. This may be done even if the user has logged out of RJS
and back in again, possibly from another site.
The sequence of events involved in using RJS are as follows. First,
the user logs in, specifying a user name, passWord, and account
number. In addition to indicating how subsequent use of RJS is to be
billed, this accounting information identifies the owner of a
particular RJE terminal. That is, the association between user name
and HASP virtual RJE terminal is unique, and only one individual is
allowed logged in under a given user name at a time.
At present, billing within RJS is not implemented, and therefore the
login account number is completely arbitrary, and user name and
password are relatively so. The first time a given user name is
used, any password may be chosen; thereafter, as long as the user
name is known to RJS, the same password must be used. A user name
remains known to RJS while he is logged in, and when he is not, as
long as he owns at least one job known to PJS. Otherwise, the user
name is discarded.
After a user is logged in, he specifies input and output file
information and requests input retrieval be initiated. He may then
log out or not as he wishes; specifically he is not required to
remain logged in during source file retrieval. A job can completed
abnormally at any stage of processing, or normally, after storage of
the last of its output. In any case, the circumstances of the final
disposition of the job are displayed to the user immediately if he is
logged in, saved for a period after its completion, and are available
to him on request the next time he logs in. This status information
is retained for at least a fixed period (currently two days), but
will be retained longer as long as sufficient storage space is
available for it.
RJS Commands - General Information
In order to simplify specification of job parameters, RJS maintains a
set of accumulators for these parameters. Each accumulator is
initially empty, and may have its contents set or referred to by
various commands. The following parameter accumulators are
maintained for each user (user name, password, and account together
are termed accounting parameters): login accounting parameter (those
specified either in the LOGIN or the USER, PASS, and ACCT commands),
source pathname, print pathname, punch pathname, source accounting
parameter, print accounting parameter, and punch accounting
parameter. In addition, associated with each job are the parameters
source, print, and punch pathname, and source, print, and punch
accounting parameters.
When the TELNET connections are first opened, RJS sends the user a
herald message of the form '300 UCSB RJS (VER. <date>) TTY
<integer>.', where <date> identifies the current version of RJS, and
<integer> identifies the user's terminal in the sense that each
TELNET connection is assigned a unique TTY number.
During the process of running a job, any of several spontaneous job
status messages may be displayed to the user. They are '240 INPUT
RETRIEVAL FOR JOB <jobid> HAS BEGUN.', displayed when the input
connection(s) have been established, '261 JOB <jobid> HAS COMPLETED
EXECUTION.', when the first of the job's printed output has been
received from HASP, '466 PRINTED [or PUNCHED] OUTPUT FROM UNKNOWN JOB
(HASP JOB NUMBER <integer>) IS BEING DISCARDED.', if printed or
punched output is received from HASP over the user's line for a job
not known to RJS, and messages eXPlaining errors such as ICP/RFC
failure, invalid job card, null source deck, missing pathname, and
data transfer network errors (see Appendix B for for a list of
possible reply id's). In addition, while in local syntax, the user
may receive messages from HASP over his virtual operator's console.
Some are responses to HASP commands issued by the user, and others
are spontaneous messages. All, however, are asynchronous to the
entering of other RJS commands.
Certain general rules hold for both sets of syntax. They are as
follows:
1. The character pair CR-LF is used as command accept to terminate
commands. Other occurrences of these two characters are
ignored, and may be used as desired for local carriage control.
2. Any number of blanks are permitted before or after any
syntactic unit (including the first and last).
3. Upper and lower case alphabetics are treated identically
everywhere except in <filename>.
4. Whenever a switch is made to the syntax not in effect, the
current TELNET modes (full or halfduplex, character or line at
a time) are saved, and reinstated when the current syntax is
again entered.
In the syntactic descriptions below, the following notation is used:
'text' denotes literal text (quotes not part of text)
<unit> denotes name of syntactic unit
<a>_<b> denotes choice of syntactic units <a> or <b>
[<a>] denotes optional syntactic unit
(<a><b><c>) denotes group of syntactic units treated as a
whole
= syntactic unit at left defined by statement on
right
The following general syntactic definitions are hereby made:
<CA> = command accept
<user name > = a string of 1 to 8 alphameric characters
<password> = a string of 1 to 8 alphameric characters
<account> = a string of 1 to 6 alphameric characters
<jobid> = a string of 1 to 8 alphameric characters,
the first of which is alphabetic.
Description of RJS Commands, Standard Syntax
The following is a list of the commands supported in the standard
syntax. Where not specified, the command's response is '200 OK'. In
those cases where it is stated that the user must be logged in, the
response '504 LOGIN PLEASE.' is displayed if the user is not logged
in.
'USER' ['='] <user name> <CA>
Specifies the user's user name for accounting purposes, initiates
login, and initializes the source, print, and punch user name
accumulators to <user name>. To complete login, this command must be
followed by a successful PASS command. The only other command
allowed before the user is logged in is BYE. The response to a
syntactically valid USER command is always '330 ENTER PASSWORD'
'PASS' ['='] (password> <CA>
Specifies the user's password to gain Access to the user's account,
completes the login initiated by a previous USER command, and
initializes the source, print, and punch password accumulators to
<password>. The response to a successful PASS command is '230 USER
<user name> OWNS REMOTE TERMINAL <integer>.', where <integer> is the
number of the HASP virtual RJE terminal owned by the user. The
following error replies are possible: '431 NEW USERS ARE NOT BEING
ACCEPTED AT THIS TIME.' if there is no free HASP terminal to assign
to the user (there is currently a maximum of 10), or if there are
insufficient other resources available to support another user; '431
INCORRECT PASSWORD.' if the specified <password> is not that assigned
to the previously specified <user name>; '431 ANOTHER USER IS LOGGED
IN AS <user name>.' - only one user is allowed logged in with a given
<user name> at a time.
'ACCT' ['='] <account> <CA>
Specifies the UCSB Computer Center account number to which the user's
use of RJS is to be billed, and initializes the source, print, and
punch account accumulators to <account>. The response to a
syntactically correct ACCT command is '200 OK'.
As previously stated, RJS billing is yet to be implemented, and
therefore the ACCT command is optional. Users and writers of user
processes are warned, however, that it will eventually be required,
and that at that point, the PASS command will return a reply id of
330, and the ACCT command will have those replies listed above under
PASS.
'BYE' <CA>
Logs the user out and closes the TELNET connections to him,
regardless of whether there are any file transfers in progress; if
there are, they continue unaltered. The response to a BYE Command is
always '231 LOGOUT C0MPLETED; TRANSFERS (IF ANY) CONTINUE.', followed
by a continuation line of 'TTY <integer> IS DISCONNECTED.'
'STATUS' <CA>
Lists the user names of those users currently known to RJS. The
response is either '100 NO USERS ARE KNOWN TO RJS' or '10O THE
FOLLOWING USERS ARE KNOWN TO RJS:', followed by one or more lines,
each beginning with a continuation reply id of four blanks, giving a
remote terminal number, the user name of the user who owns that
terminal, and the name of the site from which he last logged in.
'SYNTAX' <CA>
Causes the current command syntax to become local syntax. The TELNET
modes (full or half duplex, character or line at a time) most
recently in effect in local syntax again become effective. RJS
responds with the local syntax prompt character (currently number
sign, '#').
The remaining commands require the user to be logged in.
'REINIT' <CA>
Resets to empty the source, print, and punch accounting parameter,
the source, print, and punch pathname, and the login accounting
parameter accumulators. The response to a REINIT command is always
'204 OK'.
('INUSER' _ 'INID') ['='] <user name> <CA>
Sets the source user name accumulator to (user name>.
'INPASS' ['='] <password> <CA>
Sets the source password accumulator to <password>.
'INACCT' ['='] <account> <CA>
Sets the source account accumulator to <account>.
'OUTUSER' ['='] <user name> <CA>
Sets the print and punch user name accumulators to <user name>.
'OUTPASS' ['='] <password> <CA>
Sets the print and punch password accumulators to <password>.
'OUTACCT' <account> <CA>
Sets the print and punch account accumulators to <account>.
'INPATH' ['='] <pathname> <CA>
<pathname> = <file> _ <socket>
<socket> = [<host addr> ','] <socket number> <attributes>
<file> = <host addr> <attributes> '/' <filename>
<host addr> = <integer>
<socket number> = <integer>
<integer> = <decimal integer> _ ('D' <decimal integer>) _
('H' <hexadecimal integer>) _ ('X' <hexadecimal integer>) _
('O' <octal integer>)
<attributes> = ':T' _ ':A' _ ':N' _ ':' _ <null> _ ':E' _
':TE' _ ':AE' _ ':NE'
<filename> = 1 to 16 ASCII characters, excluding CR and LF
(codes 0 through 127, excluding 10 and 13)
Sets the source pathname accumulator to <pathname>. The <pathname>
is the means for specifying a file's source or destination; its
semantics are as follows:
1. Specification of <socket> indicates that RJS will establish a
simplex connection to the stated socket (RJS issuing the
CONNECT, user issuing a LISTEN). The data is then transferred
over this connection, with CLOSE signaling end of file.
2. If <host addr> in <socket> is defaulted, the host containing
the TELNET user will be assumed.
3. Specification of <file> indicates that RJS will contact the
standard FTP server socket (currently socket 3) at the stated
host, and transfer the data according to the File Transfer
Protocol. The <file name> referred to here corresponds to the
term <pathname> used in the FTP specification document, RFC
#354.
4. The type of carriage control and the data code used are
determined by <attributes>. The meaning of this parameter is
as follows:
':T' ASCII code, TELNET carriage control
':A' ASCII code, ASA carriage control
':N' ASCII code, no carriage control
':' identical to ':N' for input, ':A' for output
<null> identical to ':N' for input, ':A' for output
':E' identical to ':NE' for input, ':AE' for output
':TE' EBCDIC code, TELNET carriage control
':AE' EBCDIC code, ASA carriage control
':NE' EBCDIC code, no carriage control
Detailed descriptions of the transfer modes may be found
below under 'RJS File Transfer.'
('OUTPATH' _ 'OUT') <output file> '=' <disp> <CA>
<output file> = 'A' _ 'B' _ <null>
<disp> = <pathname> _ '(H)' _ ('(S)' (pathname>) _ '(D)'
Stores <disp> in the print pathname accumulator if <output file> is
either 'A' or <null>, or in the punch pathname accumulator if <output
file> is 'B'. The meanings of the options for <disp> are as follows:
<pathname> transmit-and-discard - the file is sent and
then deleted
'(H)' hold only - the file is not sent but rather
held for user intervention
'(S)' <pathname> save - the file is sent and then held for user
intervention
'(D)' discard - the file is deleted as soon as it is
produced
'INPUT' <CA>
Creates a job, stores with it the contents of the source, print, and
punch accounting parameter and pathname accumulators, and places it
in a queue within RJS of jobs owned by the user awaiting source file
transfer. When it becomes the first or only job in this queue, the
retrieval of its source file is initiated. A job identifier
('jobid') is assigned to the job and displayed to the user. The
contents of the source and print pathname accumulators must have been
set by INPATH and OUTPATH commands previous to the INPUT command. If
successful, the message '260 ASSIGNED JOBID IS <jobid>.' is
displayed, where <jobid> is that which may used in subsequent RJS
commands to identify this particular job. If the user is found to
own the maximum number of jobs (currently 5), an attempt is made to
satisfy the request by finding the oldest of the user's jobs that has
completed processing. If this can be done, the old job is deleted,
and the response to the command is '260 JOB <old jobid> IS BEING
DISCARDED TO MAKE ROOM FOR THE NEW JOB.', followed by a continuation
line of 'ASSIGNED JOB ID IS <new jobid>.' The following error
responses are possible: '360 SOURCE PATHNAME HAS NOT BEEN
SPECIFIED.', '505 PRINT PATHNAME HAS NOT BEEN SPECIFIED.', '504 NEW
JOBS ARE NOT BEING ACCEPTED AT THIS TIME.', and '504 USER (user name>
ALREADY OWNS THE MAXIMUM NUMBER OF JOBS.'
'CHANGE' <jobid> <output file> '=' <disp> <CA>
Stores <disp> as the print pathname of job <jobid> if <output file>
is either 'A', or <null>, or as the punch pathname if <output file>
is 'B', if the appropriated file transfer has not yet begun. The
following error replies are possible: '464 JOB <jobid> NOT FOUND.',
'5O4 JOB <jobid> IS ALREADY BEING, OR HAS BEEN, PRINTED.', if <output
file> is 'A', '504 JOB <jobid> IS ALREADY BEING OR HAS BEEN,
PUNCHED.', if <output file> is 'B', and '464 USER <user name> DOES
NOT OWN JOB <jobid>.'
'STATUS' <jobid> <CA>
Causes the status of the job known to RJS as <jobid> to be displayed.
Included in this display are in which stage of RJS processing the job
is ('BEING READ', 'IN EXECUTION', 'BEING PRINTED', 'BEING PUNCHED',
or 'HAS COMPLETED'), the pathname information (accounting parameters,
host name, socket number, attributes, disposition, and filename) for
those files (source, print and punch) that have been supplied for the
job, and if the job has failed at some stage of RJS processing, an
explanation of the failure. The possible responses are '464 JOB
<jobid> NOT FOUND.', and a line with reply code 161 followed by zero
or more continuation lines explaining the status of the job.
'CANCEL' <jobid> <CA>
Causes processing of the job known to RJS as <jobid> to terminate
immediately, and all record of it to be deleted. If FTP data and/or
command connections are pending or established, they are closed; if
the job is in execution, an OS CANCEL command is issued to terminate
execution. Any output from the job is lost, and a subsequent request
for status of job <jobid> will return the diagnostic that the job is
not found. The successful responses are '262 JOB <jobid> DELETED.'
and '262 JOB <jobid> WILL BE DELETED AS SOON AS POSSIBLE.'; the
possible failure responses are '464 JOB NOT FOUND.' and '464 USER
<user name> DOES NOT OWN JOB <jobid>.'
The following standard RJS commands are as yet not implemented, and
elicit the response '506 COMMAND NOT IMPLEMENTED.': ABORT, ALTER,
BACK, HOLD, OP, RECOVER, RESTART, and SKIP.
RJS Commands - Local Syntax Conventions
In addition to those general conventions discussed above, the
following rules hold for local syntax:
1. Except in certain circumstances, noted below, a period may be
used for command accept.
2. The following control characters have the indicated functions:
SOH (control A) delete last character
DEL delete last character
SYN (control V) delete last word
CAN (control X) delete entire line
EOT (control D) display current word
ACK (control F) display entire line
'?' display acceptable input forms
ESC force recognition of current word
blank force recognition of current word
3. The TELNET control characters 'you-echo' and 'I-echo' have the
desired results. 'You-echo' also has the effect of changing to
character at a time mode, if the user is not already in
character at a time mode.
Description of RJS Commands, Local Syntax
The following is a list of those commands supported in local syntax.
In those cases where no success reply is indicated, RJS responds with
CR-LF followed by the prompt character. In those cases where it is
stated that the user must be, or must not be, logged in, 'LOGIN
PLEASE.' or 'LOGGED IN.', respectively, are displayed if the user is
not in the appropriate state. When a reference is made to a response
listed under a standard syntax command, it should be noted that reply
id's are not displayed under local syntax.
'FULLDUPLEX' <CA>
Sets the user to fullduplex and character at a time modes.
'HALFDUPLEX' <CA>
Sets the user to halfduplex mode.
'LINE<-AT<-A<-TIME' <CA>
Set's the user to halfduplex, line at a time modes. The control
characters previously described remain effective, but RJS will send
no output over the TELNET connection except when the current command
line is empty.
'LOGIN' <user name> <password> <account> <CA>
Specifies the UCSB Computer Center user name and account to which the
user's use Of RJS is to be billed, logs the user in, and sets the
source, print, and punch accounting parameter accumulators to <user
name>, <password> and <account>. This command is valid only if the
user is not logged in, and has the same replies as the standard
syntax 'PASS' command.
'DISCONNECT' <CA>
Closes the TELNET connection. If the user is logged in, he is first
logged out. The effective action taken in response to an unexpected
close on the TELNET connection is that of a DISCONNECT. The response
to a DISCONNECT command is 'TTY <integer> IS DISCONNECTED.'
The remaining commands require the user to be logged in.
'LOG0UT' <CA>
Logs the user out and terminates billing of subsequent activity over
the TELNET connection to the previously effective accounting
parameters, and performs the effective action of the REINITIALIZE
command. LOGOUT does not close the TELNET connection, nor does it
affect any file transfers in progress for jobs owned by the user.
'REINITIALIZE' <CA>
Resets to empty the following accumulators: source, print and punch
accounting parameter, source, print and punch pathname, and login
accounting parameter.
'ACCOUNTING' <account parms> <CA>
<account parms> = '(' <u> ',' <p> ',' <a> ')'
<u> = <user name> _ <null>
<p> = <password> _ <null>
<a> = <account> _ <null>
Sets the source, print and punch accounting parameters to <account
parms>. Specification of <null> for any of <u>, <p>, or <a>
indicates use of the contents of the corresponding login accumulator.
'SOURCE' <account parms> <CA>
Set the source accounting parameter accumulators to <account parms>.
'PRINT' <account parms> <CA>
Sets the print accounting parameter accumulators to <account parms>.
'PUNCH' <account parms> <CA>
Sets the punch accounting parameter accumulators to <account parms>.
'SOURCE' <jobid> (<account parms> _ <null>) <pathname> <CA>
Sets the source pathname of job <jobid> to <pathname>, and the source
accounting parameters to <account parms>, if specified, or otherwise
to the contents of the source accounting parameter accumulators. If
job <jobid> already exists and its source pathname has not been
specified, the new pathname is stored; if it has been specified, it
is changed unless source file retrieval has already begun. If the
job does not already exist, a new job is created and the pathname
stored. Restrictions are that if a job with a given <jobid> has
completed processing, it must be DELETE'd before that <jobid> may be
used for a new job; a user may only alter jobs owned by him; and he
may not own more than a certain fixed number of jobs (currently 5).
If the user already owns the maximum number, an attempt is made to
delete an old job to make room for the new one, as described for
INPUT under standard syntax. The SOURCE command has the following
possible error responses: 'NEW JOBS ARE NOT BEING ACCEPTED AT THIS
TIME.', 'USER <user name> ALREADY OWNS THE MAXIMUM NUMBER OF JOBS.',
'USER <user name> DOES NOT OWN JOB <jobid>.', 'JOB <jobid> HAS
ALREADY COMPLETED.', and 'JOB <jobid> IS ALREADY BEING, OR HAS BEEN,
READ.'
'PRINT <jobid> (<account parms> _ <null>) <disp> <CA>
Sets the print pathname of job <jobid> to <disp>, and the print
accounting parameters to <account parms> if specified, or otherwise
to the contents of the print accounting parameter accumulators. The
PRINT command either creates a new job or modifies an existing one,
as explained under SOURCE, and has the same restrictions and error
messages listed for the SOURCE command, after making the obvious
substitution of 'PRINTED' for 'READ'. The PRINT command is valid
only before print file transfer begins.
'PUNCH' <jobid> (<account parms> _ <null>) <disp> <CA>
Sets the punch pathname of job <jobid> to <disp>, and the punch
accounting parameters to <account parms> if specified, or otherwise
to the contents of the punch accounting parameter accumulators. The
PUNCH command either creates a new job or modifies an existing one,
like the SOURCE and PRINT commands, and has the same restrictions and
error messages listed for the SOURCE command, after making the
substitution of 'PUNCHED' for 'READ'. The PUNCH command is valid
only before punch file transfer begins.
'DELETE' <jobid> <CA>
Identical in function to the CANCEL command in standard syntax.
'INPUT' <jobid> <CA>
Places the job identified by <jobid> in a queue within RJS of jobs
owned by the users awaiting source file transfer. When it becomes
the first or only job in this queue, the retrieval of the source file
is initiated. If the INPUT command is successful, the message 'JOB
<jobid> ACCEPTED FOR PROCESSING.' is displayed. The following error
messages are possible: 'JOB <jobid> NOT FOUND.', 'USER <user name>
DOES NOT OWN JOB <jobid>.', 'JOB <jobid> HAS ALREADY COMPLETED.', '
SOURCE PATHNAME HAS NOT BEEN SPECIFIED.' and 'PRINT PATHNAME HAS NOT
BEEN SPECIFIED.'
'JOBSTAT' <jobid> <CA>
Identical in function and response to the 'STATUS' <jobid> command in
standard syntax.
'JOBLIST' <CA>
Lists the jobid's of those jobs owned by the user.
$ <text> <CA>
<text> = a string of any characters including '?' and '.'.
Note that <CA> must be CR-LF, rather than period.
Issues <text> as a HASP operator command over the user's virtual
operator's console. See Appendix A for a description of HASP
commands and command responses.
RJS File Transfer
The <pathname> defined earlier is the means whereby the user
specifies the location and attributes of his source, print and punch
files. The means of determining a file's location have been
previously discussed; this section explains the controls the user has
over data attributes.
The parameter <attributes> specifies the type of carriage control and
the mode of transfer. For the case of transfer over a simplex
connection, this parameter has the following meanings:
':T' or ':TE' - TELNET-like carriage control. The data is a
stream of characters with embedded carriage control bytes. Page
eject is signaled by form feed, ASCII or EBCDIC decimal 12, new
line by carriage return - line feed, ASCII l3-lO, EBCDIC 13-27.
Multiple new line ('double spacing' or 'triple spacing') is
indicated by multiple occurances of CR-LF.
':A' or ':AE' - ASA carriage control. The data is a series of
fixed-length records, 81 characters on input, 133 on output, with
the first character of each record an ASA carriage control
character. The possible carriage control characters are as
follows; '+' - no line advance before print (overprint), ' ' -
one line advance (single space), '0' - two lines advance (double
space), '-' - three lines advance (triple space), and '1' - page
eject. Whatever carriage control character appears on input is
ignored.
':N' or ':NE' - no carriage control. The data is a series of
fixed length records, 80 characters on input, 132 on output. Any
carriage control generated on output is discarded before
transmission.
When file transfer takes place by means of FTP, the interpretation of
the <attributes> parameter is somewhat different. In this case the
meanings are as follows:
':T' or ':TE' - TELNET-like carriage control. The data has the
same format as for the simplex connection, and is transferred in
stream mode, file structure, and either ASCII ('A') or EBCDIC
('E') type.
':A' or ':AE' - ASA carriage control. Data is transferred in
blocked mode, record structure, and either ASCII print ('P') or
EBCDIC print ('F') type. The first character of every record is
the ASA carriage control character described above.
':N' or ':NE' - no carriage control. Data is transferred in
blocked mode, record structure, and either ASCII ('A') or EBCDIC
('E') type. As for the simplex connection, no carriage control
information is present.
In order to effect the FTP file transfer, RJS issues the following
FTP commands (in the given order): USER (if access user name has
been specified), PASS (if password specified), ACCT (if account
specified), BYTE (specifying bytesize of 8), ALLO (if outputting
file), TYPE, STRU, MODE, SOCK, and APPE or RETR.
Appendix A: The HASP Spooling System
HASP is a spooling-queuing-scheduling system used in conjunction with
IBM OS/360 to aid in processing of batch jobs. The main purpose of
HASP is to increase throughput by minimizing I/O wait time and
providing a priority scheduling scheme whereby shorter jobs are
chosen for processing over longer jobs.
There are several stages of processing, or functions, within HASP.
At any instant, a given job is either in some stage of processing, in
which case the job is said to be active, or it is waiting to be
processed by some function, in which case it is said to be queued for
that function. Jobs to be processed by a function are selected from
the queue of jobs waiting for that function, in order of decreasing
priority. A job's priority is determined by its estimated CPU tine
and volume of output. The result is that smaller jobs are selected
for processing over larger jobs, and therefore spend less time in the
system.
The HASP remote user is provided with a virtual operator's console.
Over this console he may enter HASP operator commands to display
information about the system in general, and to exercise control over
his terminal and his jobs. HASP sends messages to his console in
response to his commands, and to inform him of conditions concerning
him as they arise. HASP commands have the following general form:
$ <verb> <operand1>,<operand2>,...,<operandn>
where
<verb> = a single character verb which
identifies the general function
to be performed
<operand> = identification of the object to
be displayed or acted upon.
Zero or more operands may be present, depending on the command, and
commas are used to separate operands when more than one is used. In
general, alphabetics may be entered in either upper or lower case,
and for text outside paired apostrophes, blanks may be inserted at
any point desired. Apostrophes intended as text characters must
appear in duplicate.
Every HASP command ellicts one or more responses. The response "OK"
is used in many cases to acknowledge the command and to signify that
the requested action has been taken or initiated. In the later case,
an information message will be issued when the request is completed.
Every HASP console message begins with the text 'S HH.MM.SS' or
'S*HH.MM.SS', where HH.MM.SS is the time of day in hours, minutes,
and seconds, and in 24 hour clock.
Many commands display job status information as a response. The
format of this standard response is as follows:
jobs queued for processing:
JOB jjj jobname AW EXEC class PRIO prio HOLD
PRINT rem PURGE
PUNCH rem *DUP*
PURGE
jobs being processed:
JOB jjj jobname EXECUTING class PRIO prio HOLD
ON DEVICE dev PURGE
IS PURGING
where
jjj = HASP assigned job number
jobname = OS jobname
AW = 'AWAITING'
class = job's job class
prio = job's HASP internal priority
rem = terminal number of remote terminal
where job is queued to print or punch
dev = device name
HOLD = signifies job is in hold status, or
will be at completion of current
function
PURGE = signifies job will be purged at
completion of current function
*DUP* = signifies job cannot begin execution
until another job with same jobname
completes
The following is a brief description of those HASP operator
commands that may be issued by a remote user (for a more
complete description, see NIC #16306):
SDA Display status information on all active jobs
SDF [,rem] Display number of jobs queued for special forms
SDN [,queue] Display status information on all queued jobs
SDQ Display number of queued jobs
SCJ jjj Delete job immediately
SKJ jjj Issue OS CANCEL and delete job
immediately
SPJ jjj Delete job after current function
SDJ jjj Display job status information
SD'jobname Display job status information
SB device,pages Backspace device
SC device Delete current function on device
SF device,pages Forward space device
SDP device Display job number of job on device
SDI Display status and classes of initiators
SDLINE rem Display status of remote terminal
SDRM rem Display status of remote terminal
SDU Display status of local unit record
devices
SDM rem,'message' Display message to remote console
