**  Paramize Quadrant Upon Entering
**
**	A quadrant is initialized from the information held in the
**	Quad matrix.  Basically, everything is just initialized
**	randomly, except for the starship, which goes into a fixed
**	sector.
**
**	If there are Klingons in the quadrant, the captain is informed
**	that the condition is RED, and he is given a chance to put
**	his shields up if the computer is working.
**
**	The flag `f' is set to disable the check for condition red.
**	This mode is used in situations where you know you are going
**	to be docked, i.e., abandon() and help().
