Query: A Complete Reference Of Powerbuilder 6.0 (All Versions)

The book goes into as much detail as most CPD's need. The reference ability does match powerbuilders on-line books. But as a secondary tool the book is useful.After reading Oracle Unleashed I decided to try this book. I wasn't disapointed. Take advice and buy the book!
