44**	Device `dev1' is damaged in an amount `dam'.  Dam is measured
45**	in stardates, and is an additional amount of damage.  It should

47**	to docked mode occurs automatically if we are docked.
48**
49**	Note that the repair of the device occurs on a DATE, meaning
50**	that the dock() and undock() have to reschedule the event.
