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.
