This is the first powerbuilder book, I read that seems to be not only a compendium but delivers as well many pratical nice choosen examples. On the first look, you got the impression that this is only an adapted book to the next version, but if you really take a look you will remark many details which are carefully done. I recommend that book to all newcomers to powerbuilder as well as a to experienced developers. The index is very well done.
