DFHEPC
DFHEPC is the EXEC interface processor for program control commands. This module is invoked by DFHEIP.
DFHEPC routes a local program control request, such as LINK, XTCL, RETURN, LOAD, RELEASE, and HANDLE ABEND, to DFHPCP (in CICS versions earlier than CICS 4.1) or to a CICS Program Domain module (in CICS versions 4.1 and later). DFHECP routes remote requests to the intersystem module DFHISP.
