LIBDEF

If you use the ISPF LIBDEF facility, note the following restrictions:

• LIBDEF is not supported for the SYSPROC DD. Consequently, you must include the IT CLIST library in the SYSPROC concatenation of a logon CLIST or a TSO logon proc.
• Do not use LIBDEF to allocate the required load libraries. IT programs make dynamic calls to LE runtime routines. Using LIBDEF to allocate ISPLLIB results in S806 “module not found” abend. This is a limitation of ISPF LIBDEF.

There are two CLIST exits for LIBDEF: TIELIBDF and TIELIBFR.

• TIELIBDF is called at the beginning of IT functions such as ITINSTAL, and TIXSTART. TIELIBDF dynamically allocates ISPPLIB, ISPMLIB, and ISPSLIB.
• TIELIBFR is called at the end of some IT functions and can be used to free libraries allocated using LIBDEF. TIELIBDF and TIELIEBFR contain examples of how to use LIBDEF to allocate and free libraries.

Note: When customizing exits, use a different library that can be concatenated before the CA Gen software, ensuring that CA Gen software libraries are not modified.
