41** Paramize Quadrant Upon Entering
42**
43** A quadrant is initialized from the information held in the
44** Quad matrix. Basically, everything is just initialized
45** randomly, except for the starship, which goes into a fixed
46** sector.
47**
48** If there are Klingons in the quadrant, the captain is informed
49** that the condition is RED, and he is given a chance to put
50** his shields up if the computer is working.
51**
52** The flag `f' is set to disable the check for condition red.
53** This mode is used in situations where you know you are going
54** to be docked, i.e., abandon() and help().
