Oh come on Alan, you learn the new machine (not assembler) instructions the
IBM way, you look at what the PL/X (or whatever it is called today) compiler
generates....

Where did *I* learn?  I have, ummm, uhhh, let's just say: "connections". 
:-)

As you discovered, HLASM books describe the assembler, not the processor.

The current S/390 Principles of Operations is SA22-7201-08.
The current z/Architecture POP is SA22-7832-06.

If there's a new edition, there are new instructions.  The front chapters 
in those books (you know, the ones we all ignore?) can be very helpful. 
There may also be processor-specific publications/announcements that 
provide details - I don't know.
