All kidding aside thanks Lars...make sure to put //Lars next to this code when using it.
As far as giving Lars credit in the comments, since I noticed you wanted to give me credit for something once too jt, maybe a line in the credits at the end of the game like Programming assistance and then just list the people you want to name. I don't know specifically how Lars feels about it, but that's my two cents, I don't expect or really want any kind of specific credit like you keep suggesting, but how you give credit I guess is entirely up to you.
By the way thanks Lars, I downloaded and tried to look at some of the source with notepad, but the code was compressed so I haven't had time to explore it much yet with a different editor, but I plan to. I did look over your pdf documentation and it's infinately more complex than anything I would have ever thought of writing. An excellent example to learn from in a number of different ways. Thanks. If you have any more of these treasures buried in your hard drive collecting virtual dust feel free to pull them out anytime.
