Customizing Job Skeletons

This section explains how to tailor the job skeletons that ISMF uses to generate the job streams used by DFSMSdss, ICKDSF, IEBPTPCH, and IDCAMS.

Restrictions

You can remove variables from the skeletons, but you should make sure that a variable you remove from one part of a skeleton isn't needed by some other part.
Do not change any of the variable names in the skeletons. ISMF code is dependent on these names.
If you add variables, make sure that the names you use do not duplicate existing ones.

Finding the Skeleton You Want to Change

The ISMF skeletons for DFSMSdfp and DFSMSdss line operators and list commands are kept in their respective skeleton libraries. DFSMSdfp and DFSMSdssmembers begin with DGTK. The remaining characters in the name identify the line operator or command. Thus the member DGTKCY01 contains the job skeleton for the COPY line operator.

Note: When ISMF is installed, the skeleton library name is SYS1.DGTSLIB.

Making the Changes

There are several ways to customize the ISMF skeletons for DFSMSdfp and DFSMSdss jobs:

You can add statements to imbed skeletons of your own.
You can modify the variables in the skeletons to override the input that the skeletons get from the values entered on the data entry and job submission panels.
You can add pre- and postprocessing steps to the job stream.

For example, if you want to imbed your own skeleton in the ISMF skeleton, you begin by creating the skeleton you want to imbed. The new skeleton might contain statements that add new steps. Then you imbed the name of this skeleton in the original skeleton. The job stream that is generated from the tailored skeleton contains the new steps.
