     BASIC09 comes with a graphics extension library called GFX
which is called as a Procedure from BASIC09.  There's no reason that
GFX couldn't be redone for the Atari or any other machine, but
subject to a caveat.  The Color Computer GFX is oriented to the Color
Computer's video chip's limits (4 color sets, 256 x 192 resolution
also interfacing to Joystick is in GFX now that I'm mentioning it).
The choice would have to be made whether to use the same parameters
for portability or the relevant Atari parameters.  Personally, I
feel that GFX should be re-written to be NAPLPS based in instructions.
The NAPLPS approach (hardware independent) is the best I've seen.
