Abstract

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.

Method (b) Prior art and problems Electronic computers have various control functions in order to control input/output devices, and how to process sequential human output and asynchronous input/output within these control functions. There is a function of ``power to do''. Conventionally, a method has been used in which a processing procedure is composed of a parent task and a child task, and an asynchronous input/output control section is generally provided in the child task subordinate to the parent task to control the input/output processing routine section in the parent task. . However, this method has the disadvantage that if sequential input/output is the main focus, asynchronous input is in a subordinate relationship, and sequential input/output and asynchronous input require separate management, and sequential human output and asynchronous input are centrally managed. There is a need for an input/output processing method that can perform input/output processing in parallel with asynchronous input/output and sequential input/output in view of the above-mentioned conventional drawbacks. The purpose is to

Furthermore, the asynchronous input/output control unit 2 is provided with a work area, and the sequential output text unit 4 stores the output text sequentially, and is also provided with a work area. The input/output processing routine section 8 stores materials necessary for procedures required for input/output processing. The asynchronous input/output statement section 1 is located in the parent task, stores asynchronous input/output statements, and is communicated with the asynchronous input/output control section 2 through the PO8T/WAIT Mac4.Asynchronous input/output processing takes the above materials into the work area and executes the asynchronous input/output statement. The input/output control unit 2 performs this. The input/output processing routine section 8 is also shared by the sequential input/output statement section 4 in the same parent task, and when shared, it reads materials into the respective work areas mentioned above and processes asynchronous human output and sequential input/output. will be held. The above is generally known as an endrant (reentrant). Therefore, asynchronous human output and sequential input/output processing are executed in parallel.
