VMS Help EDIT, /TPU  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Invokes the DEC Text Processing Utility (DECTPU).  By default, this
  runs an editor called EVE (for Extensible Versatile Editor).

  Format:

     EDIT/TPU[/qualifier...] [input-file,...]

  For example, the following command invokes DECTPU (running EVE) to
  create or edit a file named JABBER.TXT in your current, default
  directory:

     $ EDIT/TPU jabber.txt

  For information about DECTPU programming, see the DEC Text Processing
  Utility Reference Manual.  For information about EVE, see the
  Extensible Versatile Editor Reference Manual or use the online help
  in EVE.
