Sebastian Theis has just released what many 83+ users have always wanted, a pretty print program like the TI-89's homescreen uses. This is not a Detached Solutions program so you'll have to download it from
http://www.softheiss.de/. This application however does work very closely with Brandon Sterner's
Symbolic application versions 1.6 and higher. You can now use Pretty Print from BASIC using Symbolic's new token pretty(. We hope to see some amazing new BASIC programs in the near future.
Update Jan 17 - Symbolic 1.7 has been released. This fixes the notorious bug when differentiating expressions with a minus sign. Sorry everyone! I was just trying to optimize code.
