A general point to all following this fascinating topic In Table 2-6, "LU Type 2 Screen Size BIND Format" in section 2.1.3.3, "Erase/Write Alternate Command" of "3174 Establishment Controller, Functional Description", GA23-0218-11[1], there is something designed thoroughly to muddy the water. I hadn't noticed it before and I wish I hadn't noticed it this time. <g>
I was going to say I've been teaching the "wrong stuff" all these years when I realised that I couldn't have been since what I taught was the way it worked - and was the way everybody else was experiencing it worked. Was the manual wrong or was it describing something that actually was compatible with the "incorrect" implementation in application programming - and 3270 emulators? Perhaps those who are really interested can go and look it up and reach their own conclusions. It concerns the way the X'7F' code in byte 24 of the BIND image is described and introduces another code, X'3F', which appears to correspond to what I - and I believe others - have described as the way the X'7F' code works.
