Have you tried plotting using exclusive OR (EOR) to do the plotting. You plot the shape twice using EOR, the second plot effectively deletes the shape just plotted. Then you recalculate the coordinates and plot twice again. In this way you do not need any CLG, which resets things each time. You set the EOR action using GCOL 3, n. and then use the appropriate plot command, eg LINE 9,0,100,100. -- Chris Johnson
