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

The IXCYQUAA mapping macro provides the format of the area that the ANSAREA parameter points to (the QUAMEM section maps the member information). If you intend to use that area, include the IXCYQUAA mapping macro in your program.
