I am doing a high (very high) level presentation for my managers who have no
MF experience. I want a simple slide. Something like:
IBM architecture is not RISC, there are nnn instructions.
nnn Privileged
nnn General
nnn Decimal
nnn Cryptographic
etc.
I've Googled and looked at some of the sites
Dave,
thank you for mentioning hlasm.com. There is no straightforward way of
counting instructions.
There are many ways to count them, many criteria by which to discern or
categorize them.
I have tried to present the instruction lists with options to
include/exclude various (sub)categories,
but
Instructions are hard to count, though instruction count isn't a
very good way to determine CISCness.
RISC tends to have a small number of instruction lengths, often 1.
S/360 through z/ have three lengths. Not too CISCy, but not RISC.
(VAX might have 14 or so, from one byte on up.)
RISC tends to

I would mention in such a presentation that the MF is the only architecture
that can reasonably pe programmed in ASSEMBLER language today,
because the instruction set is clear and straightforward and defined in
such a way that it is at the same time well performing on the machine

Bernd,
I couldn't have said this better, bravo ! I have seen slam dunk testing in
some MF environments without planning, understanding or critical thinking
skills. Maybe it's my old age.

I'd like to second that, for some reasons:
a) other machines like RS/6000 etc borrowed the RR/RX/RS instruction set
from the S/370, and they are RISC in my opinion
b) I know other machines (old German mainframes) which are definitely CISC,
and they have stack instructions or they are able to mod
Bernd,
I knew of the RS/6000 and RISC but not that it was prevalent or original on the
IBM mainframes.
