The information returned in the user-provided answer area is mapped by the IXCYMQAA macro. The data consists of a header record (mapped by MQAHEADER) and zero or more records appropriate to the type of query. See z/OS® MVS™ Data Areas in the z/OS Internet library for a description of the IXCYMQAA macro.

When retrieving information from the answer area, do not hardcode any length values for the header or various record types. Use the lengths and offsets that are included in the MQAA record itself.
