PURPOSE:To attain a unified management of the input and output processing, by processing asynchronous input and output and a sequential input and output in parallel, in performing the input/output processing in a computer by means of a task. CONSTITUTION:A slave task of an asynchronous input/output control section 2 stores an asynchronous input/output control sentence and a working area is provided. Further, a sequential input/output sentence section 4 stores a sequential input/output sentence and a working area is provided. An asnchronous input/output section 1 exists in a master task, which stores the asynchronous input/output sentence. Further, the processing of the asynchronous input/output is done by the control section 2. An input/output processing routine section 3 is used in common at the output sentence section 4 in the same master task, and when it is used in common, a material is read in each working area and the processing of the asynchronous input/output and the sequential input/output is done. The output sentence section 1 and the sequential output sentence section 4 are formed in the relation of exclusive control so as to prevent the interference of the operation of both input and output sentence sections. |
