The EXCI CALL interface

The EXCI CALL interface consists of six commands that allow you to allocate and open sessions to a CICS® system from non-CICS programs running under MVS™ , to issue distributed program link (DPL) requests on these sessions from the non-CICS programs, and to close and deallocate sessions on completion of DPL requests. This section describes each EXCI CALL command and shows an EXCI CALL example.

The application program stub, DFHXCSTB

The EXCI commands invoke the external CICS interface through an application programming stub, called DFHXCSTB, provided by CICS . You must include this stub when you link-edit your non-CICS program.
