PURPOSE:To perform processings efficiently by starting a high-class language control part if the command of an instruction of a simple language control part requests a high-class language in a device provided with the simple language control part and the high-class language control part. CONSTITUTION:A system control part 1 receives input instructions from a key input 2 and an external storage device 4 and drives a simple language control part 5 or a high-class language control part 6 through a bus line B1 and stores results in an RAM7 or 8 and displays them on a display device 3. If a high- class operation business of the high-class language is discriminated when the processing mode of the simple language is discriminated and the simple language control part 5 is started to execute operations, the high-class language control part 6 is started by a bus line B4 to execute operation processings, and results are stored in the RAM8 and are displayed on the device 3. Thus, the function of the simple language control part is improved without making this control part large-scale. |
