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