Heh heh... we did that till we puked a week ago... :-)


I don't know of anything that will do that... I usually use the old ROM Box
routine in Zoom, and make a good guess ( it usually works ).  Graph your
equation, then choose Box from the ZOOM menu - F3, F1 I think.  You may have
to zoom in once or twice at the center to find a good spot.


BTW: I am working now on a ZS program that does shading in grayscale of
equations for the purpose of graphing inequalities, systems of inequalities,
other uses for shading... the 85 fills with black and makes other lines
unusable, and the 82?/83?'s crosshatching is even worse.  If anyone is
interested please let me know.  SpyHunter beta 1 should be out to beta
testers hopefully soon, as soon as I get a rest from homework enough to put
a few more touches on.
