Which option suppresses page numbers in the output of SAS listings?

The option that suppresses page numbers in the output of SAS listings is NONUMBER. By including the NONUMBER option in the SAS procedure or at the beginning of the script, users can effectively prevent page numbers from being printed on each page of their listing output. This is particularly useful when the visual aspect of the output is being tailored for a specific purpose, such as presentations where page numbers might be distracting or unnecessary.

The other options, while they may seem similar, are not valid in SAS for suppressing page numbers. For instance, NOPAGE is not a recognized option in SAS for controlling page numbering specifically, and NOPAGENUMBER is not a standard option either. Likewise, NOPAGENUM is not a recognized directive in SAS syntax for suppressing page numbers. Therefore, understanding the correct usage of the NONUMBER option is essential for managing the formatting of output listings in SAS effectively.
