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