Called by

DFHZDSP

Description

The close z/OS® Communications Server ACB module is invoked whenever CICS® and z/OS Communications Server are being uncoupled. This may be as a result of DFHZTPX being driven as the result of a z/OS Communications Server halt command or the issue of the main terminal command SET VTAM,CLOSE|IMMCLOSE. The status of all sessions is checked and, when all are inactive, the ACB is closed.
