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. -- James Omura, Barrister & Solicitor, Toronto ihnp4!utzoo!lsuc!jimomura Byte Information eXchange: jimomura Compuserve: 72205,541 MTS at WU: GKL6
