Is my Logic wrong or QB64's ?

You can avoid border IF checking by allowing x, y to go only as close as 1 pixels away from border (but what does a screen return for a point outside it's border?)

Funny!
Case 3 : Pset(sx, sy), klr  ' no if's, ands, or buts!!!

Hey maybe your Pixel Life isn't exactly by Conway's Life Rules but it sure is pretty!

Thanks for spotting that case 3 mess up.

As for what a screen returns for a point outside it's border it's -1 as opposed to the whole value for a color.
