I think you mean $8000.

In any event, I'd wager there is probably a few K that can be gained by 
doing that simply by eliminating the redundant stuff in command 
interpretation, tokenization, and the various overhead from ramhooks. 
That would give a non-trivial speedup, too.

That would probably make a siginficant difference in the footprint but 
not so much in the floating point handling routines. The real difference 
would come from the removal of all the trig and similar functions that 
require floating point. It would, of course, make things run 
significantly faster, however.

A complete HPRINT character set (matching the hires text screen) could 
be done. (Don't even need to create the extra characters - they're 
present in the Coco3 ROM at the end of SECB).

Maybe also support for both floating point and integer variables, or 
even double precision floating point.
