BTW: Up-to-date z/OS 1.11 is still partially 31-bit and 24-bit.
As long as the backward compatibility promise is not broken
there will be AMODE24 and AMODE31 interfaces in z/OS.

That's good. However I wrote about the bad side. Many system components
are still
Radoslaw, Yes the limitation was a TSO one. But since z/OS R8 (I think)
there is a PROFILE option to place the index to the variables above 16MB.

But each user has to turn that option on. and actually for the ISPF
environment for rmm this is not a great help because it
I would also add that if you run into a constraint that's affecting you,
get a requirement in to IBM (via SHARE, via your friendly IBM
representative, or any other official channel). If 24-bit or 31-bit code
isn't causing a real-world constraint, my view is that the code should not
be changed, for

If you are at z/OS 1.7 or higher you are quite certainly running in 64-bit
mode, that is the only mode supported by these OS levels.

Dump out PSA.
Now if you are asking if a specific program is running in 31 or 64, use the
TAM instruction.

If it's 1.7, or higher, the answer is: it is.
z/OS 1.7+ only runs in 64-bit.

Yes, but I thought I remembered him saying he was running 1.7 the other day.

1.6 supported bi-modal, IIRC.
But, we jumped from 1.4 to 1.7, so I don't know.
And, we were in 64 since 2.10.

Bi-modal? You mean like MVS/XA? Or do you mean that you
could run it in ESA mode? From the 1.6 announcement:
z/OS V1.6 must execute in a z/Architecture (64-bit) mode.

There was the z/OS V1R2/3/4 Bimodal Migration Accommodation described in:
FSVO 64-bit. You could run OS/390 2.10 *and some earlier releases* on 64-bit
machines.
You're getting pedantic.
2.10 could run in 64 bit mode.
Not much different than 1.1.
But, it allowed us to test/run ISV software.
It definitely ran in 64, because our first test system moved that way, and

I may have forgotten the terminology, but up to 1.6, you could run 31, or 64.
Of course, I'm not as pedantic as others.
I never used it.
We switched to 64 at OS/390 2.10 and never looked back.

No, bi-modal ended with 1.5. 1.6 could only run 64-bit.
