Use the IXCREQ macro to construct an XCF Server request. This macro expands inline to initialize and format an area that can then be used with the XCF Client/Server IXCSEND macro to send a request to the XCF Server for processing. The client can then receive the returned response information through the XCF client/server IXCRECV macro.

For guidance information and other details on using IXCREQ with the client/server interfaces, see the IXCREQ topic in the chapter "Using XCF for Client/Server Communication" of z/OS MVS Programming: Sysplex Services Guide.
