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.
