What is the function of the LABEL statement in SAS?

The function of the LABEL statement in SAS is to assign descriptive labels to variables. This enables the user to provide more meaningful descriptions for variables, which can enhance the readability of output and make it easier for others to understand the data without needing to reference variable names directly. For instance, instead of displaying a variable named "age," a label can be assigned to show "Age in Years," offering clearer context and improving report presentation.

While other statements and functions may serve to format, rename, or summarize data, the specific purpose of the LABEL statement is solely focused on providing descriptive labels to variables. This capability is particularly useful in creating reports and output tables, where the readability of the results is critical. It contributes to clearer communication of the data’s meaning and can simplify interpretations for stakeholders or users analyzing the data.
