Qualifier

/OUTPUT
      /OUTPUT[=filespec]
      /NOOUTPUT

   Specifies the file to which the display is written (default is
   SYS$OUTPUT). The asterisk (*)  and the percent sign (%) wildcard
   characters are not allowed in the file specification. If you
   enter the /OUTPUT qualifier with a partial file specification
   (for example, specifying only a directory), SHOW is the default
   output file name and .LIS the default output file type.

   If you enter the /NOOUTPUT qualifier, output is suppressed.
