Programming Requirements

The IXLZSTRB macro provides the format of the area that ANSAREA points to. If you intend to use that area, include that macro in your program. IXLZSTRB maps each of the following types of data to be returned to the caller:

STRBHEADER maps the header section of the answer area.
STRBSTRSUMMARY maps summary information about the requested structure.
STRBSTRDETAIL maps detail information about a requested structure.
STRBSUMMARY maps summary information for a specified CLASS, LISTNUM, or event monitor controls request for a particular structure.
STRBDETAIL maps detail information for a specified CLASS, LISTNUM, or event queue controls request for a particular structure.
STRBENTRY maps entry information for a specified CLASS or LISTNUM request for a particular structure.
STRBEMCDETAIL maps EMC information for event monitor controls associated with a specified LISTNUM and maps EMC information for event queue controls associated with a specified CONID.

Depending on the request type, you might need additional macros to map the information returned by IXLZSTR.
