ABSTRACT:
In a method for modifying data loaded into memory cells of an electronic postage meter machine having a microprocessor which executes steps for a routine controlled by an external storage medium, a data modification mode is entered into by plugging a programmed, read-only memory module, which contains a program to be interpreted, into communication with the microprocessor and the program is loaded from the module into the microprocessor, a check routine is executed in a secure region of the postage meter machine for checking the validity of the loaded program, and given validity of the loaded program, the data in the postage meter machine are modified including initialization of an interpreter routine, with the interpreter routine being executed in the data modification sequence.
