Query: this book is a turkey

In stark contrast to the title, this book is NOT for professionals, at least not professional programmers, and certainly not for anyone who wishes to become a professional SAS programmer. Any secrets in this book are destined to remain secrets of the authors after the reader has read them. Consider, for example, the half page on transporting files between computers. The only "secret" revealed is that it can be done, but not a word is said as to how. Finally, the 6.08-6.10 "update" is a very brief, uninformative appendix. The book is really about Release 6.06 and before, i.e. it is seriously out of date, despite its recent publication date. This book might possibly be slightly useful to managers who need to write technobabble about why they are advocating the use of SAS as a data management environment. It will be of negligeable value to anyone who will actually be called upon to accomplish serious work using the SAS language.
