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.
