DFHZOPN executable module

Entry points

DFHZOPN1

Called by

DFHZACT

Description

The open destination module acquires storage for an RPL and NIB and BIND areas if the TCTTE does not have these resources already, and sets up the BIND image if required. DFHZOPN then issues a z/OS Communications Server OPNDST macro (or OPNSEC macro if secondary, to respond to an incoming BIND) to establish a session between CICS and the remote LU.
