Thanks. But that makes them even more expensive to implement. Which could
be a further reason as to why they weren't.

Primitive instructions such as AGH/ALGH/SGH/SLGH would not be
implemented in millicode.

On the most recent machines, as soon as you modify an instruction, you blow
away the instruction cache, resulting in degradation of performance. :(

With a suitable work area, a RENT version could be designed.

I'll put in my comment. I don't think that the current z architects are
driven by "how will assembler programmers use the architecture" any more.
Neither are they theoretical computer architects who are wedded to an
"orthogonal" instruction set. To me, many of the new instruction have been

It does look like AGH is missing. If not using register is more important
than being RENT, here is test macro program which uses MVC and AGHI:

I am out of the office today but will be checking emails. I will respond as

Well, that's disappointing. I always thought the system architects were
damn close to being infallible and omnipotent :-).
