Sorry kll, thanks for the quick reply (I was busy in a group setting when I posted), but I don’t see why a for loop is needed?
One other question… Where can " myline = grabline() " go without being in draw() or setup()? I tried placing a function call before setup but it does not run.
I did move " r = new int[6] " into setup to make it global to the program, just to clean it up.
Thanks for the compliment
