Cataloged procedures

A cataloged procedure, like an in-stream procedure, is a named set of job control statements. However, these control statements are placed, or cataloged, in a partitioned data set (PDS) or partitioned data set extended (PDSE) known as a procedure library. This enables a cataloged procedure to be invoked by any job.

Cataloged procedures can be placed in the system procedure library SYS1.PROCLIB or in any user-specified procedure library (for example JCLLIB). For additional information on procedure libraries, refer to z/OS MVS JCL Reference.

Table 1 shows an example of a cataloged procedure named MYPROC. Table 2 shows an example of a job that executes MYPROC.

Table 1. Cataloged Procedure: Member MYPROC in SYS1.PROCLIB
Job control statement	Explanation
`//MYPROC PROC`	Starts cataloged procedure
`//MY1 EXEC PGM=WORK1`	Identifies first step in procedure
`//MYDDA DD SYSOUT=A` `//MYDDB DD SYSOUT=*`	Request 2 data sets for first procedure step
`//MY2 EXEC PGM=TEXT5`	Identifies second step in procedure
`//MYDDC DD DSNAME=F.G.H,DISP=OLD` `//MYDDE DD SYSOUT=*`	Request 2 data sets for second procedure step
`// PEND`	Indicate end of procedure.

Table 2. Job that Executes Cataloged Procedure MYPROC
Job control statement	Explanation
`//JOB2 JOB ,'JACKIE DIGIAN'`	Starts job
`//STEPA EXEC PROC=MYPROC`	First step in JOB2, executes procedure
`//MY2.MYDDC DD DISP=(OLD,DELETE)`	Modifies DD statement MYDDC in procedure step MY2

Note: Before cataloging any procedure, test it as an instream procedure first.
