Ways to Use the GREPLAY Procedure :: SAS/GRAPH(R) 9.3: Reference, Third Edition

You can view, replay or manage catalog entries in two ways:

by submitting code-based GREPLAY procedure statements. The GREPLAY procedure automatically uses code-based statements if you are running in batch mode or in line mode in a non-windowing environment. See Using Code-based Statements to Run the GREPLAY Procedure.
by browsing or editing the fields in the GREPLAY procedure windows (if you are running SAS in a windowing environment). For more information, see Using the GREPLAY Procedure Windows.

If you are in the SAS windowing environment, you can toggle between the windows and code-based statements while you run the GREPLAY procedure.

For more information, see FS Statement and NOFS .
