DD Statement Names

The following provides additional information describing the special
ddnames.
Name Description
JOBCAT and
STEPCAT
JOBCAT and STEPCAT define VSAM catalogs
used for VSAM clusters. In the BIM-EPIC DD,
JOBCAT and STEPCAT also define catalogs used
for VSAM/SAM datasets. These extensions are not
available in MVS.
JOBCAT defines the catalog for the entire job
stream.
STEPCAT defines the catalog for a specific
step.
Note: STEPCAT overrides a JOBCAT definition
for that step. If used, a JOBCAT DD must
immediately follow the // JOB statement. If used, a
STEPCAT DD must precede all VSAM labels
which require that catalog. For example:
//JOB VSAM UPDATE
* //JOBCAT DD DSN=VSAM.JOB.CATALOG,DISP=SHR
* //STEPCAT DD DSN=VSAM.STEP.CATALOG,DISP=SHR
vsam labels
// EXEC PROGRAM
