|Routing the SAS Log and SAS Procedure Output|
For each SAS job, process, or session, SAS automatically creates the SAS log file and the Work library. (For a discussion of the Work library, see The Work Library under OpenVMS.) If procedures in the SAS program produce printed output, then SAS also creates the procedure output file. If they are stored as disk files, the SAS log and procedure output files usually have file types of .LOG and .LIS, respectively.
