/EDIT

   editor by entering the SET EDITOR command, the DECTPU-based
   EVE editor is invoked. Use your editor to peruse the last read
   message. When you are done, enter the appropriate command to
   quit from your selected editor. If you decide to edit the message
   and want to keep a copy of the newly edited message, enter the
   appropriate command to exit (use the EXIT command in EVE) and
   supply a file name.
