The application I want to do will use a lot of the RSBASIC as is intact. What I would 
love to do is  increase the grahics routines so that they will also support 640x480 
and 256 colors. Instead of doing the graphics as two layers like there is now, I would 
like to combine several subroutines. There are several commands lilke DRAW and 
HDRAW that I feel can be combined. The main difference in the routines is the 
resolution of the graphics screen.  

In that aspect I feel there can still remain capatabilty yet expand the ability of the 
code. Yes I am doing it for a home project and a dedicated controller.

I even thought of replacing some of if not most of the FP code and do CORDIC 
instead. That is going to need time to study if CORDIC will be faster or significantly 
slower than the current FP package in RSBASIC.
