To permit change of data, to be used in a fixed program carried out by a microprocessor (1) in accordance with a stored program (2), upon change in operating characteristics of a controlled apparatus (M), for example an internal combustion engine, an erasable programmable read-only memory (3) is provided, which is external to the microprocessor (1). The external memory (3) forms a combined address and data memory having at least one address field (4), and a vector field (5). A constant data field (7) and a table, or function data field (6) are part of the external memory (3), which data fields contain data to be addressed directly through the address field or via the vector field for not only a single type or series of apparatus, such as ICEs, but also additional engines, or engine characteristics, for example due to aging. In order to run the program by the microprocessor 1, with a changed or aged engine, then, it is only necessary to change the address of the data in the data field and/or the vector field to provide different output data for any given programming step.
