While I am happy with the L.R. I like to comment on Kens' >> The "assembler" manual I would like to see rewritten is the "Principles of Opeertations"
Absolutly.... while POP (the way it is) may have its place- I have a hard time reading about a certain instruction (when I need to). It is IMHO more than counterproductive (I dare to say confusing) for the reader (but time saving for the authors of the hardware/micro-code) to have identical instructions with only variations in a-mode and/or targets in one paragraph- this results in very subtle changes in the wording for the various flavours. I would prefer (even if this would create a manual three times as big) every instruction in a separate text. For illustration look at TRxx (xx="OT/OO/TT/TO") - or (for a simpler sample) look at AH/AHY/AH/AGHI. It would make life easier for everyone using this book if each of these instructions would be explained in a different chapter. The way it is now is that the reader is challenged to read all the fine print. To me it means reading the instructions at least twice (if not more). (and all the AH is explained in different text. -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
