JOBCAT and STEPCAT

JOBCAT and STEPCAT define VSAM catalogs to be used for VSAM clusters. In the CA EPIC for z/VSE DD facility (but not in MVS), they also define catalogs to be used for VSAM/SAM datasets.

JOBCAT defines the catalog for the entire job stream. STEPCAT defines the catalog for a step. STEPCAT overrides a JOBCAT definition for that step.

A JOBCAT DD must immediately follow the JOB statement. A STEPCAT DD must precede all VSAM labels which require that catalog.

Example

//JOB  VSAM UPDATE
* //JOBCAT  DD  DSN=VSAM.JOB.CATALOG,DISP=SHR
.


* //STEPCAT DD  DSN=VSAM.STEP.CATALOG,DISP=SHR
vsam labels
// EXEC PROGRAM
