The "shortcuts" that make up this book are ways of doing complicated things with data by using simple combinations of SAS features. Professional SAS Programming Shortcuts is not a book about how SAS works, but a book of things you can do with SAS.
The two editions contain the same chapters.
The first edition (2002) has extended coverage of efficiency issues and techniques.
The second edition (2005) is updated for SAS 9.1 with new text processing routines and techniques.
