**  DOCK TO STARBASE
**
**	The starship is docked to a starbase.  For this to work you

**
**	You get your supplies replenished and your captives are
**	disembarked.  Note that your score is updated now, not when
**	you actually take the captives.
**
**	Any repairs that need to be done are rescheduled to take
**	place sooner.  This provides for the faster repairs when you
**	are docked.
