Another issue is that many palms not yet have 8MB and even on those that do
it's not usually free for one program (however great) as there are other
uses to Palm than just Rebol. Using even 1 meg is IMHO bit inpolite.
And yes.. PalmOS memory handling is a bit strange.. (I've done some
programming to it with Quartus myself on my Palm V. Excellent program and
nice way to code natively) That memory handling is optimized for minimal
memory use and limited memory protection and it't not optimal for programs
Rebol size.
Perhaps if Rebol engine had been written differently from scratch.. But
it's IMHO more likely that Palm's get newer OS and Processors released
before that will happen.
