Customizing the Exit

There can only be one TIRCRUNC DLL in a CICS region and one TIRCRUNI DLL in an IMS system. There are notes in the sample procedure with specific information about customizing the JCL. Various steps in the procedure can be modified:

• Code Page pairs can be added to the GEN Step. Ensure that the comments next to the code page pairs are removed before executing the procedure.
• The DEFCODEP and the DEFPADCH can be set to the required values in the TIRXINFO exit. More information about this exit is covered under TIRXINFO exit in this section.
• Ensure that the data set pointed to the SYSLMOD statements for steps LKCICS and LKIMS are of type Library since TIRCRUNC and TIRCRUNI are Program Objects (format 3).
• Optionally steps LKCICSD and LKIMSD can be executed to customize the debug versions of TIRCRUNC and TIRCRUNI respectively. Again, ensure the SYSLMOD statements points to a Library.
