Customizing the Exit

There can only be one TIRSLEXT and TIRSLTMX exit in the CICS region. There are notes in the sample procedure with specific information about customizing the JCL. Various steps in the procedure can be modified.

• Not all user exits need to be modified and replaced. If a user exit compile step is removed, then the corresponding REPLACE and INCLUDE statements must be removed for the same user exit(s).
• Ensure that the data set pointed to the SYSLMOD statements for steps LKSLEXT and LKSLTMX are of type Library.
