I doubt it. (That's not the way I use PUSH/POP. I use separate
PUSH/POPs for separate functions, so I haven't tested my macros for
those scenarios.)

My macros (along with a TITLE macro and a SYSSTATE envelop macro)
were written to add text to my assembly title lines when SYSSTATE has
been set to non-default values of ASCENV, ARCLVL and AMODE64.

They also support "MAYBE" values when the various states in a
particular piece of code are uncertain. (The MAYBE values affect only
what I display in the title lines. They are not, of course,
propagated into the underlying GBLx symbols.)
