Qualifier

/OUTPUT
      /OUTPUT[=filespec]

   Requires read (R) and write (W) access to the directory in which
   the specified file is created.

   Controls the output destination of the command. By default, the
   output is the current SYS$OUTPUT device. To send the output
   to a file, use the /OUTPUT qualifier followed by the file
   specification.

   If the file specification does not include the file name or file
   type, the defaults SHOW and .LIS are used respectively.
