If bit PSAZARCH is on then z/OS is running in z/Architecture (often
referred to as 64-bit).
This bit will always be on for z/OS 1.6 or later, might be on for OS/390
R10 through z/OS 1.5, and never on prior to OS/390 R10.

z/OS 1.5 (not 1.4) was the last release that could also run in ESA (31-bit)
mode. If it's z/OS 1.6 or higher, you know for sure you're running in
z/Architecture (64-bit) mode.

Hi Radoslaw,
The are also still some systems running z/OS 1.4 ;) in 64 bit mode on a z
Series machine.
So?
I wrote "9672 AND z/OS 1.4-". It doesn't preclude the above.
Of course one could complement the answer with information about

It's easy: it is always 64-bit.
There is small chance that you find 31-bit machine (9672) and z/OS 1.4
