100% pen using a list This program goes from left to right, then back and down. So it goes from top left to bottom right. To determine the x and y of any dot, it can be complicated. I used trial and error to find it, but after a while, I came up with [ (x mod 200) - (y * 200) ] to plot a point. Its a 200 x 200 grid
use the arrow keys For mouse control, see inside and replace "px" and "py" under the main forever loop as the main parameters with the mouse blocks next to it feel free to make a game with this [good luck ;)]
