DFHFCFS

DFHFCFS is part of the file control component. DFHCFS processes requests to enable, disable, open, and close files. Such requests may originate from explicit requests (either CEMT or EXEC CICS SET), from implicit requests (such as implicit open), or from requests made from CICS internal processing.
