Syntax:

      /LOG [= file-specification]
      /NOLOG

  Use /LOG to create a list of the given names of all of the dictionary
  directories, subdictionaries, and objects copied.

  The file specification is a standard VMS  file  specification  naming
  the  file  into  which  the log is written.  The default file type is
  .LOG.  If you use /LOG without specifying a file, DMU writes the  log
  to SYS$OUTPUT.  With /NOLOG, no list is created.

  The default is /NOLOG.
