IBM System/360 20 User Manual

SYSxxx
-This operand specifies the symbolic
address of the tape drive on which the
tape is 1II0unted. (For a list of
symbolic addresses, see the description
of the ASSGN statement.)
This operand specifies the number of
tape marks to be skipped. It may be
anyone of the numbers 1 through 999.
The number of tape marks to be skipped
(n) is counted from the present
pos.ition of the tape and may be anyone
of the numbers 1 through 999. It must
take into account the tape marks
associated with the labels, as well as
the file tape marks.
REW
--This operand specifies that the tape is
to be rewound to the load point.
Not~: If, in a set of job control
statements, a FILES control statement and
an ASSGN control statement refer to the
same symbolic 1/0 address, the FILES
statement must follow the ASSGN statement.
The JOB control statement indicates to the
Job Control program that a set of job
control statements follows. It is used to
place the name of the program to be
executed next into the communication region
of the Basic Monitor program in main
storage.
The JOB control statement has one of the
following formats:
r-----r------~ -,
IName 10p.Code 10perands I
r-- I -+-----------------1
III IJOB Iprogram-name I
r---+-----+------------------f
III IJOB I RPG,program-name I
L ___ ~ _____ -J.- ___ _
JOB control statements of the first format
can be submitted either to the card Job
Control program or to the tape Job Control
program. When submitted to the tape Job
Control program, the operand ~f~Bra~=~~~~
specifies the name of the object program,
included in the core-image library, to be
executed next. The card Job Control
program checks whether the operand is
present, but ignores it and loads the
physically next program.
.J
JOB control statements of the second
format are submitted to the tape Job
Control program. In this format, the
operand ££Qg~~~~~~~§ specifies the name of
a source program written in the RPG
language whic~ is to be first compiled and
then executed immediately (i.e., without an
intermediate Job Control run) •
In both formats of the JCE control
statement, the program name is not
restricted in length. However, if the
length exceeds six characters, only the
leftmost six characters are recognized.
Note: Normally, the JOB statement is the
fIrst statement of a set of job control
statements. Only LOG, NCLCG, and PAUSE
statements may precede the JOB statement.
The LOG control statement is used to
instruct the Job Control program to list
the job control statements on the printer
assigned to SYSlOG. It also causes the
listing of tape error statistics on SYSLOG
if generated by an OPTN control statement,
provided the Job Control program is
reloaded after execution of the problem
program. If a ESCA job on which error
statistics were collected has been run, the
LOG control statement also causes listing
of ESCA error statistics. The LeG control
statement is the first statement that is
listed. listing is continued in the
following Job Control runs until a NCLOG
statement is encountered.
The LOG control statement has the
fcllowing format:
Iii ,
I Name lOp. Code IOFerands I
l----+-----t--------------------l
1// ILOG I I
L ___ ~ ________ ~
]!ot§_.1: A LOG control statement may
precede the JOE statement in a set of job
centrol statements.
J
Note 2: A lOG control statement is ignored
Ii-~~~ printer is not assigned to SYSLOG.
~~!§_l: If the job for which the LOG
statement is issued is the first job after
IPL, or if NClOG was specified during the
previous job, the first LOG control
statement in a set of centrel statements
causes the printer to skip to a new page.
The NClOG control statement is used to
instruct the Jot Control program to
discontinue the listing of jot control
statements on SYSLOG. The NOLOG control
statement is the last statement that is
listed.
Not§: When tape and/or BSCI error
statistics are collected and aNaLOG
ccntrel statement is in force, a programmed
halt occurs. The operator can then decide
whether or not error statistics are to be
printed.
