If the program is in AR mode, issue SYSSTATE ASCENV=AR before IXCQUERY. SYSSTATE ASCENV=AR tells the system to generate code appropriate for AR mode.

If you use REQINFO= any option except COUPLE, include the IXCYQUAA macro in the code to map the data returned in ANSAREA or FEATAREA.

If you use REQINFO=CF, REQINFO=CF_ALLDATA, STR, or STR_ALLDATA, you need to include the IXLYNDE macro in the code to map the hardware identification information associated with a coupling facility.
