When the CICS® global user exit XPCFTCH is used to intercept a PL/I routine by providing an alternate entry point, CICS uses the address returned in ceecics_ruentry_real if it is available. It is supplied to XPCFTCH as the new PCUE_REAL_ENTRY parameter. You can also provide a Language Environment CEESTART with the following:

• The CEESTART eyecatcher
• A pointer to a CEEMAIN with a MAIN address pointing to your replaced MAIN

There is no need for a CEEINPL, CEEBETBL, CEEBLLST, and CEESG010. Refer to the program initialization and termination information in z/OS Language Environment Vendor Interfaces for details about the format of CEEMAIN and CEESTART.
