Qualifier

/OUTPUT
      /OUTPUT[=filespec]
      /NOOUTPUT

   Controls where the output of the command is sent. If you do
   not enter the qualifier, or if you enter the /OUTPUT qualifier
   without a file specification, the output is sent to the current
   process default output stream or device, identified by the
   logical name SYS$OUTPUT.

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

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