DFHAPRT

DFHAPRT is the relay program that routes transactions to the proper remote CICS address space. When a transaction is routed to another system, the program associated with it is always the relay program DFHAPRT, regardless of the name specified in the program option. Beginning with CICS/ESA Version 4, DFHAPRT replaces DFHCRP.
