** Paramize Quadrant Upon Entering

** 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().
