Depends, Bill, on when you were there. He started writing them (I think) 2 or 3 years ago. (I used to teach there, BTW)
If you're talking about the one's we used in the classes, those are a bit different, as they are designed for use in a learning environment and don't touch on all the capabilities.
Gary, you're right. Mastercam is THE most popular in shops AND schools without a doubt, and without any
real competition (according to Cimdata). It's always been extremely powerful, and with the release of X coming soon, I can say as a beta tester, that it will take an even bigger lead next year.
