IBM System/360 20 User Manual

5Y5003 and the symbolic address for the
last work tape.
If 5YS002 or SYS003 refers to the same
drive as the symbolic address for the last
work tape, a halt occurs and the code 1C41
is displayed before any data is written on
the input tape. This enables the user to
save his input data and mount another tape
on the drive.
In a tape-resident system run, the drive
assigned to SYSRES must not be assigned to
any other symbolic device address.
SY5000 -- Required.
Refers to the tape drive on which
the primary output tape is
mounted.
5Y5001 -- Optional.
Refers to the tape drive on which
an alternate output tape is
mounted. (See the section ~E~=
cial Considerations for Multi-
volY!ii~=:!n:EQ1=and- Ol!nut F il~s-=-l
SYS002 -- Required.
Refers to the tape drive on which
input tape 1 is mounted.
SYSOO 3 -- Re qui relj except for s equ ence
checkin'j and/or reblocking only.
Refers to the tape drive on which
input tape 2 is mounted.
SYS004 -- Optional. Refers to the tape
drive on which input tape 3 is
mounted.
SYS005 -- Optional. Refers to the tape
drive on which input tape 4 is
mounted.
SYS006 -- Optional. Refers to the tape
drive on which input tape 5 is
mounted.
CONTROL STATEMENTS
If the Sort/Merge program is to be executed
under control of the card-resident system,
job control statements need be issued only
if functions of the Job Control program are
required.
Whenever execution is to be controlled
by the tape-resident system, job control
statements must be issued.
The following job control statements are
used in conjunction with the TPS sort/Merge
program:
// JCB SGBT
// ASSGN
/1 VOL
// TPLAB
II EXEC
Required.
Required for any symbolic
address whose device
assignment in main storage
is to be changed.
Required for each tafE file
on which standard label
checking is to be
performed.
Required whenever a VOL
statement is issued.
Required.
Any other job control statements, such
as OPTN, LOG, NOLOG, or FILES statements,
may be included in the set if the corres-
ponding functions are to be requested.
The TPS Sort/Merge program requires the
fcllowing control statements:
SORT or MERGE -- Required for a sorting or
merging job, respectively.
RECORD Required.
INPFIL
Optional.
OUTFIL Optional.
OPTION
Optional. Required
for
Restart runs.
MODS
Cptional. Used if user
routines
have been
added.
END Required.
Must be the
last statement.
These statements are written by the pro-
grammer. The operator should ensure that
all required statement cards are present.
USER ROUTINES
If the user wishes to include his own rou-
tines, the assembled routines (including
the END card) must be
a) inserted in the Sort/ferge program deck
(see Figure 10) if the card-resident
system is to be used; or
b) placed behind the Sort/Merge control
cards in the hopper of SYSRDR if the
tape-resident system is to be used.
The tape error statistics option can be
requested by including a // OPTN control
statement during the preceding Job Con-
trol run (280 bytes of main storage will
be used).
