If your program is in AR mode, issue the SYSSTATE ASCENV=AR macro
before IXLLSTE. 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 IXLYLAA and IXLYLCTL in your program
as necessary. Table 1 lists these
macros, the information and areas they map, and the particular IXLLSTE
requests and parameters they apply to.
