I miss my original POP ... I think it was like a half inch thick ... maybe 3/4. I know there are many here older than me, but my first assembly code was in 74. It was all pretty straightforward back then.
Now I look at the doc ... and then I made the mistake of actually looking at the intel doc I linked ... OMG And I do remember that wording you quote below :-) Never did figure out what they were getting at ... -----Original Message----- From: IBM Mainframe Assembler List [mailto:[email protected]] On Behalf Of Michael Stack Sent: Friday, November 14, 2014 3:23 PM To: [email protected] Subject: Re: Redesigning the Principles of Operation Manual Correctness is the most important, and most difficult to achieve, characteristic of PoO. An example: in my nine-years-old e-copy of PoO, there is in Appendix A a section on sorting instructions (p. A-52 in my edition). The headers and first sentence read: -------------------------------------------------------- Sorting Instructions Tree Format Two instructions, COMPARE AND FORM CODEWORD and UPDATE TREE, refer to a tree - a data structure with a specific format. -------------------------------------------------------- The problem is that execution of CFC has nothing directly to do with trees, and anyone attempting to understand those instructions will be seriously misled. What follows is a pretty-much-accurate description of how trees are used in the sort assist, but comprehensibility is sacrificed. (I should say that Dan knows of my concern, and this may well have been corrected in later editions.) This comment is intended solely to point out how much more difficult it is to write accurate mainframe technical language today than it was fifty years ago.
