In this Green Numbers data tutorial I show you how to use macros in SAS. With macros you can make your code more reusable and flexible. Reusing code can save you a lot of time and reduce clutter. Macro programming can seem daunting at first, especially if you’re new to programming, but if you focus on and practice the basics and build out from there, I promise you’ll find this skill very rewarding.

This is the third video in the SAS macro series. In this video I’m going to show you how to use if-then-do logic and loops to that will allow you to process large volumes of data with very little code. In previous videos I showed you how to create and use a macro variable, and how to use blocks of code to do repetitive tasks.
