In 20+ years of heavy assembler coding, I never needed to store and
restore the condition code, until now.
I have some 'standard' macros I use that allow me to turn some debug
code on and off during testing. Yesterday, I was using some of this code
and had a program failure due to the fact that it uses code that sets
the condition code. The program code has many places where a BALR
function returns not a R15 value, but instead returns a condition code
setting.
So, what methods do some of you use that will equate to a save and
restore a condition code? My code will be in a macro, so it can be a
little 'dicey'/'unreadable' if needed.
