  41 **  LONG RANGE OF SCANNERS
  42 **
  43 **      A summary of the quadrants that surround you is printed.  The
  44 **      hundreds digit is the number of Klingons in the quadrant,
  45 **      the tens digit is the number of starbases, and the units digit
  46 **      is the number of stars.  If the printout is "///" it means
  47 **      that that quadrant is rendered uninhabitable by a supernova.
  48 **      It also updates the "scanned" field of the quadrants it scans,
  49 **      for future use by the "chart" option of the computer.
