Description

DFHFCFR is the central module in the file control component. It handles file control requests issued by DFHFCEI (requests from application programs), or by other CICS modules (internal file control requests). DFHFCFR ensures that the file is both opened and enabled, acquires an FRTE as necessary, performs request validity checking, and then routes the request to the appropriate access-method dependent module (DFHFCBD for BDAM, DFHFCVS for non-RLS VSAM and also for update or browse requests against a CICS-maintained data table, DFHFCRS for RLS VSAM, and DFHFCDTS for all other data table requests).
