HANDLE ABEND is used to activate, cancel, or reactivate an
exit for abnormal termination processing. You can suspend
the command by means of the PUSH HANDLE and POP HANDLE
commands.When a task terminates abnormally, CICS searches
for an active abend exit, starting at the logical level of
the application program in which the abend occurred, and
proceeding to successively higher levels. The first active
abend exit found, if any, is given control.

Answer / sri

The EXEC CICS® PUSH HANDLE command allows you to nest your
condition-handling code. For example, when calling a
subroutine, you might want a completely different set of
EXEC CICS HANDLE CONDITION commands while in the
subroutine. (EXEC CICS PUSH HANDLE enables you to suspend
all current EXEC CICS HANDLE CONDITION, IGNORE CONDITION,
EXEC CICS HANDLE AID, and EXEC CICS HANDLE ABEND commands.
This can be useful, for example, during a branch to a
subroutine that is embedded in a main program.)

Normally, when a CICS program calls a subroutine, the
program that receives control inherits the current HANDLE
commands. These commands might not be appropriate within
the called program. The called program can use PUSH HANDLE
to suspend existing HANDLE commands.

Use PUSH HANDLE therefore, to save your present set of
HANDLE commands unchanged while you use a new set in the
routine. On exit, you can reinstate the original set of
HANDLE commands by using a corresponding POP HANDLE.
