  37 **  LONG RANGE OF SCANNERS

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