How do you insert comments in SAS code?

In SAS, comments are essential for documenting and annotating code, making it easier to understand for anyone reviewing or maintaining the code in the future. The correct method to insert comments in SAS is by using the /* comment / style. This format allows you to create multi-line comments easily and can span several lines. Everything between the opening / and closing */ is treated as a comment and will be ignored during execution.

This method is particularly useful when you want to include detailed explanations or temporarily disable sections of your code without deleting them. The flexibility of being able to write comments over multiple lines enhances readability and maintainability.

Other methods for comments in programming languages, such as a single line comment initiated by a symbol, are not applicable in SAS. The other options presented do not conform to SAS syntax and would either trigger errors or be ignored entirely.
