Paper 248-31 Programming with the keep , RENAME, and drop Data Set Options Stephen Philp, Pelican Programming , Los Angeles, CA ABSTRACT One of the more frustrating things for a new user learning SAS can be the multitude of ways of accomplishing the same thing, each with its own subtleties. The topic of dropping, keeping and renaming variables in data sets is no exception. Using a DATA step, there are two ways of manipulating variables for keeping, dropping, or renaming: DATA step statements and data set options. First we will review the basic workings of the DATA step, which will help you understand how each approach differs, which will then help you to create more efficient code and avoid some potentially costly mistakes. INTRODUCTION As you likely know, a SAS data set is a table. It has rows (observations) and columns (variables). Besides adding and deleting rows, the modifications you can make to the structure of a table are adding columns, deleting columns and renaming columns.
