Programming Requirements

If your program is in AR mode, issue the SYSSTATE ASCENV=AR macro before IXLCACHE. SYSSTATE ASCENV=AR tells the system to generate code appropriate for AR mode.
Include the IXLYCON mapping macro in your program. This macro provides a list of equate symbols for users of XES services and exits.

Include mapping macros IXLYCAA, IXLYCANB, IXLYCCIH, IXLYCRRB, IXLYCSCS, IXLYCUNB, IXLYDEIB, IXLYNSB, IXLYDNNB, IXLYWOB, and IXLYWORB in your program as necessary. Table 1 lists these macros, the information and areas they map, and the particular IXLCACHE requests and parameters to which they apply.
