The Query Answer Area supports several levels of information that IXCQUERY returns. Certain coupling facility and structure requests might provide data that was not returned when the IXCQUERY service was first made available. For these request types, you can specify the level of information you want with the QUAALEVEL parameter on IXCQUERY. The QUAALEVEL parameter is available with version 2 of the IXCQUERY macro. The system returns base QUAA information when you specify QUAALEVEL=0 on your request; the system returns level-1 QUAA information when you specify QUAALEVEL=1 on your request and level-2 QUAA information when you specify QUAALEVEL=2 on your request. You should be aware of the type of output that you are requesting and be able to process it correctly. IBM® recommends that you use the level-1 level of IXCYQUAA in case additional new data is returned by the IXCQUERY service. Note that the level-1 IXCYQUAA records are larger than the level-0 IXCYQUAA records.

Table 1 lists the IXCYQUAA structures that support the level-1 level of IXCYQUAA information. See the IXCYQUAA macro in z/OS® MVS™ Data Areas in the z/OS Internet library for a description of the information returned.
