Counters in FOR statements
My program prints out 360 lines. I need to print them out 20 at a time, pause, and ask the user if they want to continue. If the answer is yes, it would print the next 20. I already have the initial counter, for my calculations. Can I have two counters in my FOR statement? How would I do that?
Also, is there a better way to display $ values? I can't seem to get them to justify right, and I have all of the zeros in there.
