/OUTPUT[=file-spec]
    /NOOUTPUT

   Controls where the output of the command is sent.   If  you  do  not
   enter  the  qualifier,  or  if  you  enter  /OUTPUT  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 /OUTPUT with a partial file specification (for example,
   /OUTPUT=[JONES]),  HELP is the default file name and LIS the default
   file type.  If you enter a file specification, it  may  not  include
   any wildcard characters.

   If you enter /NOOUTPUT, output is suppressed.
