Wouldn't THAT be MORE far-reaching? !:-|

Also, I'm amazed at your knowledge of _just_where_ GEM places _what_ within its 'guts'! 

Besides someone RE-reading the source code (from scratch, as it were);
is there any place these things _are_ documented?
In other words, IF we were to "loose" John Elliot, where could the "rest of us" (<-- to steal a phrase!) find out about these things that YOU know?

Sincerely,

Thomas Clayton

  It's not quite as far-reaching as that. What it involves is rewriting all 
the video drivers, so that they store the palette values in their code segment
(which is common to all programs) rather than their data segment (which gets
duplicated every time a program opens a new graphics workstation).
