Draw Operations 7-11
Procedures for using PT.OFF( (point off, DRAW POINTS, item
2) to turn off (erase) a point and PT.CHANGE( (point change,
DRAW POINTS, item 3) to toggle (reverse) a point on and off
are the same as for PT.ON(.
When you use these instructions from the Home screen or a
program, you must specify the X-coordinate and the
Y-coordinate of the point as arguments for the instructions.
PT.ON( turns on the point at (X=X,Y=Y). PT.OFF( turns the
point off, and PT.CHANGE( toggles the point between on and
off.
