Sas Programming II: Manipulating Data With the Data Step Course Notes

As you may know, the book is almost useless without exercise files. If you buy my book, I can give you the exercise files supplement to the book. I also made note cards to study for taking SAS Base exam. If you buy my book, I can give you these cards for free. I have both new and old books, but I am selling the new one here. Thanks for considering the purchase.
