    Default Re: hangman game

    Your post doesn't ask a question, and you've still got an active question regarding this program, one which has a response that you never replied to. Locking this. Please reply to Norm, and if you post a question here, please actually ask a question that is separate from the code so that it can easily be seen to be a question. You'll also want to read the FAQ to learn about use of [code] [/code] tags so that your code will show its formatting.
