Abstract
Upon receipt of a write request to an external storage device 6 from a user program 1n, a control program 2 stores the data in a vacant area within an asynchronous input and output buffer group 31, and generates, when it is determined by examining an asynchronous input and output task management table 5 that there does not exist an asynchronous input and output execution task having a priority identical to the priority assigned to the user program 1n, an asynchronous input and output execution task having a priority in question. The asynchronous input and output execution task 4n having a priority identical to the priority of the user program 1n takes out the data from an asynchronous input and output buffer group 3 based on the storage location and the data size within the asynchronous input and output buffer group 31 delivered from the control program 2, and writes the data to the external storage device.
