PURPOSE:To exactly execute coding conversion at the time of zone coding by setting a fixed axis of coordinate, a zone number and a table number and executing the zone coding at a sample point with the aid of a vector from the fixed of axis coordinate. CONSTITUTION:An axis of coordinate is fixed at an origin 0 and 0. The consecutive sample points are shown the vectors A-C from the origin. The difference vector AB and BC between the neighboring two sample points are shown by using vectors from the origin of the two sample points and executed the zone coding. As the vectors of each sample point from the origin and the difference between the two points are expressed a zone code and a symmetry coordinate within a zone by using a zone number table, the consecutive sample points can be treated equally with an absolute coordinate.
