What is the function of the PROC PRINT code in SAS?

The function of the PROC PRINT code in SAS is to display observation numbers and all variables in the specified data set. When you use PROC PRINT, it generates a formatted output of the data, showcasing each observation along with its corresponding variable values.

This procedure is particularly useful for quickly reviewing the contents of a dataset, as it provides a straightforward way to see the data in a tabular format. In essence, PROC PRINT serves as a vital tool for data inspection and validation, allowing users to visually confirm the structure and content of their datasets.

The other options do not accurately reflect the PROC PRINT functionality. For instance, PROC PRINT does not delete a data set, create new variables, or modify existing data, as its primary role is solely to present existing data for analysis and review.
