About User Exits

CA‑PanAPT provides these types of user exits:

Member Existence Exit
Inventory Edit Exit
MSL Exit programs
Security Exit

You specify all four exits. Exits one through three are specified for each Library Code on the panels in Library Code maintenance. The fourth exit is the Security Exit. It is specified on the Control file.

This appendix describes the parameters passed to each type of exit and the return codes the exits use to communicate with CA‑PanAPT. This is the information you need to write your own exits.

The sample exits provided with CA‑PanAPT are provided in source form on the APTEXSRC data set. The ones with member name prefixes of APAS are written in Assembler language. The ones with prefixes of APCS are written in LE/390 COBOL.

The LE/390 COBOL compiler options, DYNAM,DATA (24), should be used when compiling LE/390 COBOL exits for CA‑PanAPT.
