Thanks. Helpful info here: http://www.tachyonsoft.com/inst390o.htm
If I had nothing better to do I would do a Web page with two tables: 1. Every mnemonic and the HLASM MACHINE() level at which it became available. Source would be HLASM OPTABLE(LIST). 2. Every model number and the corresponding HLASM MACHINE() and C/C++ ARCH() level. The information is available in the manuals, but it is not organized in a way that works well for me (FWIW). The question I am repeatedly trying to answer is "my customer has a model xxx -- dare I use mnemonic ABC, and/or how do I set MACHINE() to make sure I stay out of trouble?"

The descriptions of each of the added "facilities" documented elsewhere in the PoOP usually also includes a table of which instructions were added or enhanced, or at least a listing of those instructions. Below I have pasted a list which I prepared for my own curiosity (admittedly incomplete and possibly incorrect) of which edition of the PoOP corresponds to which z/Arch machine.
