If your program is in AR mode, issue SYSSTATE ASCENV=AR before
you issue the IXLFCOMP macro. ASCENV=AR causes the system to generate
code appropriate for AR mode. For more information about the SYSSTATE
macro, see z/OS MVS Programming: Assembler Services Reference ABE-HSP.
Include the IXLYCON mapping macro to generate the equate symbols for the return codes.
