On z/OS systems today YREGS is just a simple assembler macro introduced to
MVS in 1992 as part of DFSMS V1 (5695-DF1) which consists of simple general
register equates like this:
R0 EQU 0
R1 EQU 1
Etc. up to R15
I would post the entire current z/OS version from SYS1.MACLIB but it is
marked as a copyrighted source so I didn't.
It probably made its way into later versions of one of VM's system MACLIB's,
but not having access to any of those I can't tell you which one.

Sorry for the cross posting - but has anyone got the source for this
macro they can copy and paste to me?
Or does anyone know where it is found on the sixpack?
That's one I've not come across.
If you tell us what you need it for (or if possible, what it does), it
might be easier
to suggest places to look for it or possible replacements to use instead
of it.

Peter Coghlan.
