Syntax:

      /[NO]HISTORY

  Use  /HISTORY  to  facilitate  the  creation  of  history  lists  for
  dictionary  directories  and  subdictionaries  as  you  create  them.
  /HISTORY is the default.   Use  /NOHISTORY  to  create  a  dictionary
  directory  or  subdictionary  with  no  history  list.   If  you  use
  /NOHISTORY, you can still create history list entries later,  but  it
  will take slightly longer.
