+**  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().
