Syntax:

      /SOURCE

  Use /SOURCE to copy the source text of dictionary  objects  into  the
  specified file.

  If you specify /SOURCE, DMU copies the source text of  the  specified
  dictionary  objects into the file.  If the dictionary object does not
  contain source text, DMU does not create it.   If  you  want  DMU  to
  create source text, use /RECORD instead of /SOURCE.

  You should not use /SOURCE with the /RECORD option.  If you  do,  DMU
  ignores /SOURCE.

  /SOURCE is the default.
