Details

The FILEMSGS option applies to physical files that are referenced in either a FILENAME statement or function or in a LIBNAME statement or function.
If FILEMSGS is in effect and you try to assign a data set that is allocated to another user, SAS generates detailed error messages explaining why the allocation failed. Under TSO, the messages are written to the display. The display is cleared and the messages appear. You must press ENTER to return to your session in the windowing environment. In batch mode, the messages are written to the job log.
If NOFILEMSGS is in effect, you still receive some error messages in your SAS log, but they might not be as detailed.
