Yes, I had forgotten about SIO/HIO/TIO and was reminded of those by
your first post. I can't recall if I ever personally wrote a SIO
instruction. Most of the channel programming I ever did was at the
EXCP level, so i don't recall writing a SSCH instruction either.
As for the ISAM compatibility interface in VSAM, I think that went out
around the same time as ICF catalogs came along.
I agree that most vanilla application level programs written for S/360
would probably run on a z10 today. IBM took great pains to maintain
backward compatibility.

DEBE is one that I remember particularly, because of the acronym DEBE:
"Does Everything But Eat". But I only remember it as a stand-alone program.
