We still (effectively) have them with the bitwise BIFs %BitAnd, %BitOr, etc.

If reminiscences are in order..

Anyone remember RPG's BITON, BITOFF ?

Once upon a time I used them to construct op codes for a Wenger
printer that was able to print reverse image text (white on black).

Hey!? Microfiche was not just for the /34!? I worked for Zink and
Katich when I was just a babe, and I remember going through the S/38
microfiche.? Ah, those were the days... patching IBM programs to make
our own commands.

Jon,

Oh no, PL/MI is nothing like assembler (which I'm well aware you know).
I'm talking 370 and (does anyone remember it?) the S/34. Oh those
were

the

days, microfiche for the operating system and away you go :)

"Assembler" as in PL/MI Bruce ? I suspect that even MI would be too
high level if you really want to bit twiddle!

Interestingly had the original question been about C or MI I could
understand it since they still have utility. It was ancient RPG
that

got me

and (at the time) I didn't know we were talking V5R4.
