One more thing...

The formulas and their syntax were the most difficult for me to grasp. They are just different enough from VFP to make things confusing at times. Once you use the formulas and write your own over time, things make sense and get easier as you go. But I would get a book that covers formulas since they can be the hardest part of learning Crystal. I think you can also use VB commands and Crystal will understand some of those, but I have never tried it or know that much about it.
