I have thought about writing such a thing -- actually a bit test, but the logic is similar -- but I did not do it, and the immediate need for me has now passed.
Not real tricky. Someone on this list who writes assembler more on a day-to-day basis than I do should be able to whip out a prototype in no time.

I made one but I think it could be better due to performance reasons. Note: the bit index should be passed thru a register, not a value. I mean something like below using the TBIT macro to set on the bit 12 of ARRAY: LA R1,12 TBIT ON,ARRAY,(R1)
