Download the free NoteTab Lite or Crimson Editor and install the software. Open a SAS program in NoteTab or Crimson Editor to view a SAS program. Using Windows Explorer locate the program and run the SAS program by right-clicking and using Batch Submit with SAS 9.2. Load the .log and .lst files into NoteTab or Crimson Editor. Try this a couple of times to get the feel for how this works. This is sometime called running SAS in batch mode.
