Use the following format to start SP.EXE at the DOS prompt:
----------------------------------------------------------------------------------------

 Syntax:

 SP INFILE [outfile] [/d]

          The default extension for the executable file is .EXE.  The current 
 directory and drive are used unless otherwise specified with the file names.
 If the outfile is not specified, SP.EXE will automatically create back-up
 copies of the INFILE executable (.EXE) and overlay (.OVL) files. The back-up
 files will use .EXK and OVK extensions, respectively.  Use the /d option to
 retain the original time/date stamp on the executable file.
