	* progmodes/fortran.el (fortran-mode-map): Change "Join
	Continuation Line" to "Join Line".
	(font-lock-keywords-1): Add "cycle", "exit".

1998-10-14  Emilio Lopes  <Emilio.Lopes@Physik.TU-Muenchen.DE>

	* progmodes/fortran.el (fortran-join-line): Use
	`delete-indentation' instead of issuing an error message if not on
	a continuation line.  Provide for joining several lines using
	prefix arg.
