Plus42 Equations, Preview Release

[JohanNeven]

Regarding GRAPH functions, there is already a good part that works on this fantastically flexible screen. PIXEL and AGRAPH work across the screen. From run mode you can use ROW+/- and COL+/- to adjust the screen resolution so that graphs with arbitrary resolution can be drawn. Using ROW+/- and COL+/- is not (yet?) possible from within a program. This Plus42 calculator outperforms the HP42s in all areas. Fantastic!
