Abstract:
A method for processing variable service data structures in a processing module, comprising the steps of:providing a processing module having a microprocessor and a program memory accessible by said microprocessor, and storing an operating program in said program memory for operating said microprocessor; providing a non-volatile service data memory in said processing module and dividing said service data memory into a first memory area and a second memory area; dividing said second memory area into a plurality of memory sub-areas and storing variable service data, having an effective date, comprising calculation tables and display texts, at respective addresses in said memory sub-areas; storing a root table for said service data in said first memory area, said root table containing table items respectively associated with pointers for said addresses; and accessing said second memory area from said microprocessor exclusively through said root table within said operating program by selecting, within said operating program, a table item and supplying said service data to said microprocessor from said second memory area from an address identified by the pointer for the selected table item.
