Application exit routines are defined to VTAM during ACB OPEN. The following exit routines could be used by the application for NJE using SNA.

SCIP

The SCIP exit is scheduled by VTAM to handle BIND, UNBIND, and SDT requests.

LOSTERM

The LOSTERM exit is scheduled for normal session termination and for a session failure. The application should either immediately terminate or quiesce the session, based on the completion code in the RPL.

TPEND

This exit is scheduled when a HALT command has been entered or VTAM is abnormally terminating. If a normal HALT is requested, the session should be terminated after all activity has quiesced. For HALT NET,QUICK and VTAM termination, the session should be aborted by the application (using TERMSESS or CLSDST).

NSEXIT

VTAM calls this exit with a CLEANUP RU if the session has been lost.
