In a message dated 97-09-28 19:11:16 EDT, you write:

<< Um...  Why would you want to put them in B and C?  Isn't there a CLine
call?
  If not, and you know that x and y are integers <256, you can say:
 
  call _rclx
  call _convOP1     ;Is my case right?  dunno...  check the include file
  ld b,l
  call _rcly
  call _convOP1
  ld c,l
 
 If they're not integers <256 (because maybe the window is not [0,127] by
 [0,63]) then you need to scale/translate it by messing around with OP1 in
 between the _rclx and the _convOP1 (same w/ y)

ok so there's a cline call but how do l tell it what coordinates to draw the
line from?
