To Anyone Who can help:
        My pseudop-programming/graphics class must write a
program in C to draw a line. "No prob" I said... I would just 
modify the GR.7 drawing program in _INSIDE ATARI BASIC_ t
draw in GR.3, and I'll figure out the pattern/algorythm
the DRAWTO command uses. I found a pattern, but I can't 
figure it out the way it works (i.e. a nice mathematical
formula to get the next point on a line).  Does anyone
know just how the DRAWTO command works? My guess is that the
answer is either in BASIC or the OS.  But Im machine language
illiterate, and I dont have a dissasembler (I woudnt know 
the answer if it were starring me in the face in machine l.)
Any help is greatly appreciated. Thanks ahead 'o time!

sincerely,
Anthony Falcone
