Object-oriented visual program development system for handling program entity including pre-processing function and post-processing sections

摘要

A program development system which develops a program sequence by generating a diagram composed of a combination of icons, and which can apply an object-oriented scheme to the development of an application program for a parallel, real time processor. Each program entity symbolized by one of the icons includes a pre-processing section coded in a programming language for determining parameters in a message issued to an object; a function section for storing information about a linkage between the icon symbolizing the program entity and a procedure included in one of objects in an object library; and a post-processing section coded in a programming language for interpreting a message sent back from the object. When executing the program, each program entity is linked with the procedure in the object in the object library. This makes it possible to reduce coding labor, and to improve the quality of the program.
