This book is known reverently in the development shop as "The Bible". Have you ever run into a FoxPro"ism" that should work one way, but functions another? Grab for "The Bible" and right there is an in-depth description of the bug and possible workarounds. Don't attempt any serious VFP work without this book. Excellent layout and easy reference to VFP functions, commands, as well as excellent coverage of SYS(). An invaluable reference for Visual FoxPro 3.0, but don't overlook it if you're still using FoxPro 2.6 or have moved on to Visual FoxPro 5.0.

Granor and Roche do an excellent job of explaining the treasures and pitfalls of VFP3. I found this book after I had been banging my head against a particular problem for several days, and was able to find the answer immediately, where no other book I had checked gave the answer. They document both how VFP3 works, and how it _should_ work. Most of the book still applies to VFP5, and presumably it will still be good under Tahoe.

As the subtitle says, this covers the things you wish someone had put in the documentation - with explanations.
It covers the problems, too - which is what makes this book so valuable. Look out for the nice big bug artwork next to the things that don't quite work as reasonable people expect it to.
Still relevant for Visual FoxPro 5.0, highly recommended.
