ABSTRACT:
A calculator for determining postage or shipping fees which has a bus-oriented microprocessor structure having several memories, including a read only memory with programmed quadrangles corresponding to geographic areas represented by the three most significant digits of ZIP codes. This memory allows a computation of a distance-related value to be performed for each shipment between a destination ZIP code and an originating ZIP code. The distance-related value is converted to a zone by means of a look-up table. The zone, as well as a carrier selection, define a piece-wise linear curve to be used for fee calculation. Using an equation related to distance and having weight of a parcel defined by a scale, on which the parcel rests, the shipping fee may be calculated. Once the fee is calculated, special services may be added. The calculator may be changed from a calculating mode to a load mode wherein cost and weight numbers are entered by a user to define the break point or end point of linear segments which make up rate curves for each zone for a particular carrier. Each carrier may have different types of service, all having different rate curves for different zones. All may be defined by means of end points and break points for linear segments or complete straight lines with end points.
