I haven’t tried this; it’s an off the cuff suggestion but anyways...
Maybe define an alias for IEFJFCBN in MACLIB and have your #OCEWA macro either
invoke the alias name or generate the 176-byte area depending on the value in
&SYSNEST

Hi All,
I have a problem...
There's an IBM macro ("IEFJFCBN") that's called by another IBM macro
("IECDSECT"), but I want to temporarily change IEFJFCBN such than
when IECDSECT calls it, the changed IEFJFCBN only generates a buffer
without also generating all the JFCBnnnn fields.
To do that I have written an envelop macro ("#OCEWA") for calling
IECDSECT. But before calling IECDSECT, #OCEWA creates an inner macro
definition for "IEFJFCBN" that generates the 176-byte buffer without
also generating the JFCBnnnn fields. Then when IECDSECT invokes
IEFJFCBN, it gets my copy instead of IBM's copy. So far, so good.
Normally, once created, inner macros survive the termination of their
defining outer macros, and are available for the rest of the
assembly. Normally, that's a good thing...
BUT... In this case, once I've invoked #OCEWA, I then want to discard
the temporary IEFJFCBN such that subsequent invocations (outside of
#OCEWA) get IBM's copy, not mine.
So Once my IEFJFCBN is no longer useful, I want to purge it. The
problem is, I don't know how to do that.
Can anyone help me with this?
Thanks,
