IXCMSGC allows a user to query information about incomplete message-out requests, about completed message-out requests that are pending notification, or about messages that have been saved using the IXCMSGC Save Message service.

The system returns the information requested in a storage area that the requestor provides. The storage area, specified by the ANSAREA parameter, must either be in the caller's primary address space, or in an address or data space that is addressable through a public entry on the caller's dispatchable unit access list (DU-AL), or in a common area data space. The contents of the answer area are mapped by the IXCYMQAA macro.
