SUPJSCAT—suppress JOBCAT and STEPCAT DD statements

The SUPJSCAT function suppresses the action of all JOBCAT and STEPCAT DD statements in a job.

JOBCAT and STEPCAT statements allow circumvention of the cataloging structure that is implemented by the data center. JOBCAT/STEPCATs allow data sets to be cataloged in a catalog that does not have an entry in the z/OS master catalog. These data sets are then accessible only through a JOBCAT/STEPCAT in the JCL (or a hardcoded volume ID); the data sets cannot be located by the normal z/OS catalog search process. This situation can create problems if personnel are not aware of the JOBCAT/STEPCAT requirements.

JOBCATs and STEPCATs are not supported by DFSMS; use of these DD statements in an SMS-managed system causes a JCL error.

SUPJSCAT provides a method of monitoring jobs for JOBCAT/STEPCAT usage without causing problems (in simulation mode).
