•
The CONFG statement, if required, must
~recede
the first TPLAB statement for a
job.
•
All other job control statements may
a~pear
in ani order between the JOB and
EXEC statements.
The JOB statement and the EXEC statement
are required in any set of job control sta-
tements.
If it is intended to suspend sys-
tem operation without terminating the sys-
tem run, a PAUSE control statement must be
issued.
When the Job Control program
encounters a PAUSE statement before it has
read a JOB statement, i t causes an immedi-
ate halt.
In this case, the Job Control
program expects a set of job control state-
ments to be read as soon as system opera-
tion is resumed by pressing the Start key
on the CPU console.
When a PAUSE statement
is encountered between a JOB and an EXEC
statement, the Job Control program finishes
reading the set/of control statements
issued and causes a system halt immediately
before the loading of the program is to
begin.
In this case, the Basic Monitor
expects to load the program associated with
the set of job control statements as soon
as sjstem operation is resumed by pressing
the start key on the CPU console.
The programmed-halt coues that may be
displayed during the execution of the Job
Control program as well as the appropriate
restart
~rocedures
are described in the

PREPARATION OF A CARD-RESIDENT SYSTEM RUN
The following steps must be taken to initi-
ate a run of the card-resident system.
1.
Place into the hopper of the loading
unit
(2501
if attached; otherwise,
2520
Card Read-Punch or primary feed of 2560
MFCM) :
a)
the IPL deck,
b) the appropriate ASSGN card for SYS-
RDR (behind the IPL deck) ,
c) the Basic Moni tor deck
(behind the
ASSGN card for SYSRDR) •
2.
Place into the hopper of the device
assigned to SYSRDR:
a) phases
00,
01 and 02 of the Job Con-
trol program deck
b) the cards containing the job control
statements (for system initiation
and for the first job), and
c) phase 03 of the Job Control program
deck.
EQ1g:
The job control statements
must include a DATE statement.
d) the problem program deck (or several
stacked decks with Job Control decks
and job control cards where
required) •
]Q!g:
A Job Control deck and job
control cards are not required for
second and subsequent Frograms in a
job stream when the configuration
and I/O-device assignments are the
same and program-dependent job con-
trol statements are not used.
3.
Press the Start key{s) of the loading
unit and the device assigned to SYSRCR.
4.
If the printer is to be used, prepare
and start this device.
5.
Prepare and start the I/O devices used
by the first problem program to be
executed.
6.
Set the Register-Data/Address switches
on the CPU console to an even main-
storage address between hexadecimal
009C and the end-of-storage address
minus hexadecimal
0052.
7.
Set the Mode switch on the CPU console
to PROCESS.
8.
Press the Load key on the CPU console.
Figure 3 shows the arrangement of input
fer a card-resident system run.
DESCRIP!ION CF CUTPUT
The output obtained from object programs
executed under control of the card-resident
system depends entirely on the type of out-
put specified in these programs and, there-
fore, must be identified with information
supplied by the programmer.
