If anyone would like a copy of the seven-page paper "that IBM should
have written" and that describes (1) all of the restrictions I
discovered and (2) a coherent example of how one might modify AMODE=24
code, please send me a private note. Hopefully you can see my e-mail
address above - it's charlesm at mcn dot org. There's no catch - I'm not
trying to sell you anything, and while the paper is copyright, the code
examples and techniques are freely usable.
It's not an assembler or xxAM tutorial; reasonable assembly language and
xxAM knowledge and skill is assumed.

Subject: Reference for DCB coexistence with RMODE 31 programs?
I've got some assembler subroutines (non-reentrant) in which I rather
lazily embedded QSAM and BPAM macros. That of course limits the code to
RMODE=24. I would like to move the necessary control blocks to AMODE=24
STORAGE and let the code be RMODE ANY31. (The code currently runs AMODE
ANY with no problems.)
Question: is there any reference that provides a succinct statement of
the steps necessary? (If not, why not, but that's a different topic.)
Yes, I know each macro is separately documented in the two DFSMS
manuals, but I mean, is there any overview of the conversion steps
necessary?
Along the same line, I have a small paper available for free:

Kind regards,
