Understanding the Difference Between DROP and KEEP Statements in SAS

The Difference Between DROP and KEEP Statements in SAS

In SAS, DROP and KEEP statements are used to manipulate dataset variables. The key difference lies in their functionality:

KEEP Statement

The KEEP statement is used to specify variables that you want to retain in a dataset, while excluding all others. It selects only the specified variables for further processing or analysis.

DROP Statement

On the other hand, the DROP statement is used to exclude specific variables from a dataset, retaining all other variables. It omits the specified variables from the dataset, allowing you to focus on the desired information.

It is important to remember that both DROP and KEEP statements can impact the structure and content of your SAS datasets, so it's crucial to use them carefully based on your requirements.
