  49 **  Paramize Quadrant Upon Entering
  50 **
  51 **      A quadrant is initialized from the information held in the
  52 **      Quad matrix.  Basically, everything is just initialized
  53 **      randomly, except for the starship, which goes into a fixed
  54 **      sector.
  55 **
  56 **      If there are Klingons in the quadrant, the captain is informed
  57 **      that the condition is RED, and he is given a chance to put
  58 **      his shields up if the computer is working.
  59 **
  60 **      The flag `f' is set to disable the check for condition red.
  61 **      This mode is used in situations where you know you are going
  62 **      to be docked, i.e., abandon() and help().
