  47 **      A summary of the quadrants that surround you is printed.  The
  48 **      hundreds digit is the number of Klingons in the quadrant,
  49 **      the tens digit is the number of starbases, and the units digit
  50 **      is the number of stars.  If the printout is "///" it means
  51 **      that that quadrant is rendered uninhabitable by a supernova.
  52 **      It also updates the "scanned" field of the quadrants it scans,
  53 **      for future use by the "chart" option of the computer.
