I'm trying to make a simple dos version of snake. I know how to do all the simple dos graphics, but I have a problem with controlling the snake. When I change directions, I have to press a key. The game is inside a loop, so if I need keyboard input, it stops the game until I press something. What code do I need to keep the snake moving, but also ready for user input? PLEASE HELP! I don't need the whole program, I got most of it. I just need to know how to do the moving part.
