I can't see the advantage of rewriting MOVE and indicator usage in existing programs. New programs should use the new techniques and old programs should >> be changed as needed when they are maintained. But where's the justification for rewriting the existing programs. At a practical level a MOVE does the same >> thing as an assignment ans SETON does the same thing as a BIF. You're not making the program run any differently, you're only making the source look
different

Actually, a GUI is a DRAIN on performance. Think about it: the original
Macintosh, and the Tandy 6000 were both based on the 68000. The 6000
could run up to 6 concurrent users (5 of them on VT-100-compatible
terminals). The Mac 128 barely supported one, and indeed, the first
truly viable Mac was the Mac Plus.
Running DOS apps, an 8MHz 8086 was a speeding bullet. Running GEM apps,
it was barely adequate. Running even the earliest versions of WinDoze
was completely impractical, and running anything beyond WinDoze 2 (maybe
3.0) was outright impossible.
Any hypothetical native GUI for the 400 would have to be based on the
graphic extensions to the 5250 data stream, with each terminal handling
all its own rendering.
