CICS Command Level Preprocessor Support
CA Dynam/FI fully supports the CICS command level preprocessor, despite the
inconsistent way in which the preprocessor performs I/O. BLKSZ=OPT support
provides major performance improvement and improved I/O utilization.
Sample JCL for COBOL:
// DLBL FISYSPH,'SYSPCH.FILE',2,SD,BLKSZ=OPT,SYS008
// EXTENT SYS008,SCRTCH,1,0,256,10
// ASSGN SYS008,DISK,VOL=SCRTCH,SHR
// EXEC DFHECP1$
.
.
COBOL PROGRAM
/*
// DLBL FISYSIN,'SYSPCH.FILE',2,SD,BLKSZ=OPT,SYS008
// EXTENT SYS008,SCRTCH,1,0,256,10
// ASSGN SYS008,DISK,VOL=SCRTCH,SHR
// EXEC FCOBOL
/* Sample JCL for ASSEMBLER:
// DLBL FISYSPH,'SYSPCH.FILE',2,SD,BLKSZ=OPT,SYS008
// EXTENT SYS008,SCRTCH,1,0,256,10
// ASSGN SYS008,DISK,VOL=SCRTCH,SHR
// EXEC DFHFA1$
.
.
ASSEMBLER PROGRAM
/*
// DLBL FISYSIN,'SYSPCH.FILE',2,SD,BLKSZ=OPT,SYS008,LRECL=80
// EXTENT SYS008,SCRTCH,1,0,256,10
// ASSGN SYS008,DISK,VOL=SCRTCH,SHR
// EXEC ASSEMBLY
/*
Note: For Assembler, the LRECL=80 parameter must be specified.
For other programs the LRECL=80 parameter may be specified, but it is not
required.
The file 'SYSPCH.FILE' can be CA Dynam/D-controlled, then the EXTENT and
ASSGN may be omitted.
