You can use the comment statement anywhere in a SAS program to document the purpose of the program, explain unusual segments of the program, or describe steps in a complex program or calculation. SAS ignores text in comment statements during processing.

CAUTION:: Avoid placing the /* comment symbols in columns 1 and 2. In some operating environments, SAS may interpret a /* in columns 1 and 2 as a request to end the SAS program or session. For details, see the SAS documentation for your operating environment.
