Therefore, ifyour SAS program includes a LIBNAME or FILENAME statement that refers to a localpath (such as a location on your C: drive), then you receive processing errors.Instructors have the ability to store SAS data sets and other data files on the SASserver. If your instructor has taken advantage of this feature, then you will receiveeither a LIBNAME statement or a FILENAME statement from your instructor that youcan use to access the appropriate data.Note: LIBNAME or FILENAME statements are case sensitive.

Copy them or enterthem in exactly as they are shown to avoid permissions errors.If you do have local SAS data sets that you want to use, then it is recommended that youupload them.
