Just catching up from being away for weeks, there's one thing that
hasn't been mentioned in this long thread about RMODE 64:
Why is this even needed?
A load module library filling a 3390-2 will just about fit below the
bar. It greatly simplifies things to run RMODE 31 AMODE 64, with most
of the data above the bar. Then none of this RMODE 64 discussion is
relevant.
Oh, I suppose if your program is written in one of those bloatware
languages that are used for apps on cellphones, where every rinkydink
trivial app is 30 MB, and big apps can be 500 MB, then you might
possibly need RMODE 64. There is no possible way that anything
written purely in z assembler would ever need RMODE 64. If your data
doesn't fit below the bar, move the data, not the program.
Part of the product that I work on is in Metal/C, which apparently
generates all code as RMODE 64 AMODE 64.
