Phillip,
I just wanted you to know that I was not ignoring your request. I just wanted a chance to test my program before I sent it off to you, and this is the first chance I've had to test it. The problem is that there have been enough changes to PPL since I first wrote the program that it no longer works. I will get it fixed up, but it might take me a couple of days between other things. Thanks for your patience, and in the mean time I'd suggest playing around with PPL just to get your feet wet.
