PURPOSE:To enhance the operation rate of a computer system by constituting the system so that a defective part of an operating system can be corrected without interrupting the computer system. CONSTITUTION:An operating system actuates a correction program 6, an execution segment 5 is read successively into a main memory 4, compared with a correction segment name of the correction program 6 immediately before the execution, and when they are equal to each other, the execution control is shifted to the correction program 6, and a read-in defective segment is corrected by the correction data of the correction program 6. In this case, 'only execution possible' of a segment attribute is changed to 'writable' and corrected by the correction data, and after the correction, the segment attribute is returned to 'only execution possible' again. Subsequently, the execution control is returned to the corrected execution segment 5 from the correction program 6, and the operation of a regular operating system is executed. In such a manner, the operation rate of the computer system can be enhanced.
