Dedication

This book is dedicated to all the employees of SAS especially those who have worked together in writing all the underlying code that makes up SAS^®  Software without which neither the company SAS nor this book would be possible. In addition, I'd like to dedicate this book to my wife, Jeannie, and our three children—Spencer, Rachael, and Lissa whose support and love has helped me progress in both life and in my career.
