In the context of PROC PRINT, what happens if you do not use the VAR statement?

• A. Only selected variables will be printed
• B. No data will be displayed
• C. All variables in the data set will be displayed
• D. Only numeric variables will be shown

Answer: (C)

In PROC PRINT, when the VAR statement is omitted, the procedure defaults to displaying all the variables in the specified dataset. This means that every column from the dataset will be printed in the output, regardless of whether they are numeric or character variables. Using PROC PRINT without a VAR statement is a straightforward way to get a complete overview of all the data in a dataset. It’s important to recognize that the other options do not accurately represent the behavior of PROC PRINT without the VAR statement. Only selected variables will not be printed since omitting the VAR statement does not impose any restrictions. Additionally, data will be displayed because a complete print of the dataset is the default behavior when no specific variables are indicated. Lastly, the procedure does not limit the output to only numeric variables; instead, it includes all types of variables present in the dataset.
