Acknowledgments

This book would not have been possible without the contributions and hard work from many people. First, I'd like to thank the authors and designers of the first edition of this book. I had the good fortune to start a second edition from an excellent foundation. I'd like to thank editors, Julie Platt and John West. To Julie, thank you for initiating my working on this book project. To John, thank you for coordinating the development of this book and for working with me on how to focus and organize the examples.

Thanks to the SAS technical reviewers for carefully reading the material and providing thoughtful suggestions: Michele Austin, Amber Elam, Marty Hultgren, Mark Jordan, Lynn MacKay, Charley Mullin, Ginny Piechota, Linda Reznikiewicz, Julia Schelly, Jason Secosky, Jan Squillace, Sally Walczak, and Kim Wilson. And, I'd like to give a special thanks to Amber Elam for reviewing the book several times.
