If an abnormal termination occurs while VTAM® is processing under an application program task, the degree of recovery is operating system dependent.

The abnormal termination might be restricted to affect only a part of the application program, as described in Isolation of errors.

When VTAM abnormally terminates, VTAM rejects application program requests, including CLOSE ACB.

If possible, the TPEND exit routine is scheduled with reason code 8.
