Def Card - Control Data Corporation 3300 Reference Manual

7.3.3
*DEF CARD
60229400
CORE=x 1-3 decimal digits describing the number of 512 word quarter
pages required for the run. If object program is larger than
the compiler, the user must reserve additional memory.
CORE=35 is suggested as a minimum for normal compilation.
Optional fields that may be required by the object program follow:
CLASS=
E
Emergency
B Background
I Input/Output (usual class for COBOL jobs)
C Compute
peq= peq is a hardware type number, decimal digits to the right of =
indicate the quantity of equipment of this type required to handle
user files. Drives must be reserved for all Class
B
files.
Unlt
record devices must also be reserved.
( $*DEF(P1 ,P2' •.. )
These cards are used to allocate, open, or close user files. Complete descrip-
tions appear in the MASTER Reference Manual. *DEF cards are not required
for COBOL compilation or execution except:
User must OPEN a nonstandard file for INPUT, LIST, PUNCH, XECUTE,
or COPY, and he must specify the dsi for the file on the $UCBL card.
User must allocate all permanent online mass storage files which are not
in existence when execution starts. Other mass storage files are allocated
internally during program execution when the programmer includes the
FILE LIMITS clause in the source program. OPEN source statements in
the user program open all allocated files except a rerun dump file on mass
storage, this must be opened with a *DEF card prior to object time. If
the file to be allocated is blocked, the user must add eight characters to
the block size for an I/O control system mass storage block header.
