Calculate the following: K3(2 1 0) = (x_sign x_hi x_lo) - x-coordinate of the sun or space station K3(5 4 3) = (y_sign y_hi z_lo) - y-coordinate of the sun or space station K3(8 7 6) = (z_sign z_hi z_lo) - z-coordinate of the sun or space station where the first coordinate is from the ship data block in INWK, and the second coordinate is from the sun or space station's ship data block which they share.
