+**  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.
