There are two main items that can be labeled, variables and values.once created these labels will appear in the output of statistical procedures and reports that you may produce from SAS. They are also displayed by some of the SAS/GRAPH procedures.
The program below reads the data and creates a temporary data file called auto

. The labeling shown in this module are all applied to this data file called auto.
