Understanding Proc Compare

In this module we look at the SAS procedure Proc Compare. We see how it is used to compare datasets with one another and find any differences between them. This is a very useful procedure in making sure the outputs from your SAS programs are correct and is mainly used for validation purposes.

We will also learn how to read the compare results and really understand what SAS is telling us. Also we will look at some of the useful options that we can use with Proc Compare such as the LISTALL option.
