This document describes how to copy all members from one Partitioned Data Set (PDS) to a new PDS and changing a parameter in all target members, using CA File Master Plus for MVS.

This example is going to change the CLASS parameter in a JOB card only - without changing MSGCLASS for instane.


Because INFORMAT(JCL) is being used in the following sample, the IF applies for the whole JOB statement - doesn't matter how many lines the JOB statement has.

And due to using " CLASS=P" and ",CLASS=P" (with a leading space or comma), MSGCLASS won't be changed in your JOB card.

Please check each line, but it should be sufficient, if you change the yellow highlighted text. The sample copies all members from an existing PDS to a new PDS. If the new PDS exists, it will be deleted first.
