Example

 $ SET NOON
 $ DELETE  *.SAV;*
 $ SET ON
 $ COPY  *.OBJ  *.SAV

     This command procedure routinely copies all object modules
     into new files with the file type .SAV. The DELETE command
     first deletes all existing files with the .SAV file type, if
     any. The SET NOON command ensures that the procedure continues
     executing even if there are no files with the .SAV file type
     in the current directory. Following the DELETE command, the SET
     ON command restores error checking. Then the COPY command makes
     copies of all existing files with .OBJ file type.
