SAS (R) Macro Language Course Notes

This book does a great job of showing examples of SAS macro coding techniques. It includes how to create macro variables using %LET, Call Symput and Proc SQL, as well as passing parameters, %IF statements (and when you need to use it versus a data step IF statement), %DO loops, and debugging. Most importantly it shows whats going on behind the scenes which explains why my programs work (or don't work!) the way they do which the log doesn't always tell you.If you can't take the class, buy this book!
