This is a trick for GATO which allows you to instantly move the
 submarine to any coordinate on the map without having to spend your
 time (or the ship's fuel) sailing there!
 
 To get instantly to any map coordinate:
 
 KEYS --- EFFECT
 C --- (Goes to Chart)
 Z --- PASSWORD>
 PAED <Rtn> --- COORDINATES>
 XXXXX,XXXXX --- (Goes to coordinates XXXXX,XXXXX on Chart)
 
 The XXXXX above can be any decimal number, and the two values should
 be separated by a comma but with no spaces in between. The first
 number is the East distance, the second the North distance, from
 lower left corner of Chart. 0,0 is the lower left hand corner of the
 map, but the sub sinks if you go there (or anywhere less than about
 10,10). Each Box on Chart Map is 5000 X 5000, and each hatch mark on
 Quadrant Map is 1000.
