THE POWER OF PROC FORMAT
The FORMAT procedure in SAS® is a very powerful and productive tool. Yet many beginning programmers rarely make use of them. The FORMAT procedure provides a convenient way to do a table lookup in SAS. User-generated SAS Formats can be used to assign descriptive labels to data vales, create new variables and find unexpected values.
PROC FORMAT can also be used to generate data extracts and to merge data sets. This paper will provide an introductory look at PROC FORMAT for the beginning user and provide sample code (ver 6.12) that will illustrate the power of PROC FORMAT in a number of applications.
