Introduction

To program effectively using SAS, you need to understand basic concepts about SAS programs and the SAS files that they process. In particular, you need to be familiar with SAS data sets.

In this lesson, you'll examine a simple SAS program and see how it works. You'll learn details about SAS data sets (which are files that contain data that is logically arranged in a form that SAS can understand). Finally, you'll see how SAS data sets are stored temporarily or permanently in SAS libraries.
