Each PLOT command draws a line from the previous location to the specified coordinates. Specifying zero for color does not draw a line although it does change the location.

This example establishes the drawing position at line 100, element 200 on the current frame.
PLOT A, B, 1, 3

This example draws a line in graphics color level 2 from the previous position to a new line coordinate in the variable A, and an element coordinate equal to A plus 3.
