title: What's the difference between the "rename" function and the "label" function in ´SAS´ and what are the use cases of each?
body: <p>SAS has both a <code>rename</code> function and a <code>label</code> function. Both of which appear to change the names of the data columns you are working with. Could anyone explain to me why there are two functions in SAS that appear to do the exact same thing?</p>
  <p>Thanks!</p>
