I was already thinking along ARKoenig's suggestion and revised my code to use arrays.

It was working pretty well until I made some minor changes. Now it loops non-stop without any prompt for the player to make a play. I am sure it is a small error, but I can't see it. I don't remember the changes I made just before it started looping continuously. I hope someone else's eyes can see it. Here is my new code. Thanks in advance. I apologize in advance for less than ideal indentation.
