What file extension is used for SAS program files?

The file extension used for SAS program files is .sas. This extension indicates that the file contains a SAS program, which is a script or code written in the SAS language that can be executed within the SAS environment. Programs with this extension may include data manipulation, analysis tasks, and various procedures specific to SAS.

In contrast, the .sas7bdat extension is specific to SAS datasets that store data in a proprietary format, not program code. The .txt extension is a general text file format that may contain plain text but wouldn’t include SAS-specific syntax or structure. The .dat extension is often used for raw data files that might not have a defined structure or format that SAS directly recognizes as program code. Therefore, .sas is the correct and most appropriate file extension for SAS program files.
