  The Delete History... menu item deletes all or part of
  the library history.  CMS writes the deleted history
  records to a file named HISTORY.DMP in your current
  default directory.

  Delete History... does not delete the library creation
  history record.

  When you choose Delete History..., a dialog box appears,
  allowing you to specify options for the history you are
  deleting.
