High-level language (HLL) exits run in an LE/370 enclave
which CICS® VT establishes with
CEEPIPI. This places certain restrictions on the semantics of how
your exit ends.
In the IBM® Language Environment® Programming
Guide manual, terminating a program in any of the following ways will
result in an abnormal termination:
- C
- exit(), abort(), or signal handling function specifying a normal
or abnormal termination
- COBOL
- STOP RUN statement
- PL/I
- STOP or EXIT
A U313x in module VIDIPIPI abend is the likeliest outcome.
