Ok I need some help with this assignment it's due tomorrow and you have to draw a picture in the editor and run it as a program. I've got the picture down but theres a problem. I want to get the colourback option to stop at a certain point more specifically at (1,64), (2,64), (3,64) and so on. Here's a pic. How do I get the colourback to stop at the 64th column?
