IMS-Related Skeletons
This appendix tells you about ChangeMan ZMF ISPF skeletons and variables used by the IMS Option.
Introduction
You can modify the behavior of the ChangeMan ZMF IMS Option by customizing ZMF skeletons, exits, and panels, and by using XML Services to access ZMF functions and data.
This appendix tells you where to find information about ChangeMan ZMF ISPF variables used by the IMS Option, and it lists skeletons involved in IMS component processing.
When you customize a ChangeMan ZMF component, preserve the original code by copying the component from the delivered library into a custom library, and edit the component in the custom library. If you customize and assemble an exit program, ensure that the customized load is written to a custom load library.
For general information about customizing ChangeMan ZMF, see the ChangeMan ZMF Customization Guide.
ISPF Variables for the IMS Option
When IMS Option batch job JCL is built by ISPF file tailoring, information from the following sources is passed to file tailoring in ISPF variables:
-
Global administration
-
Application administration
-
IMS Option administration
-
Package master
-
Component history
ChangeMan ZMF ISPF variables and tables are listed in member #VARLIST in the CNMZMF SKELS library. ISPF variables and tables used exclusively by the IMS Option usually have names that start with \&IMS...
Use #VARLIST to find ISPF variables that contains the information you want for a customized skeleton.
