PROGRAM CONTROL STRUCTURE GENERATING DEVICE

PURPOSE:To improve the productivity and the reliability by leading the module structure of a program from the data structure to divide functions and modules with the data flow of data flow design as the center. CONSTITUTION:An operator inputs the instructions of edition and display of a data flow to be inputted from a mouse 2 or a keyboard 3. An editing part 7 in a central processing unit 1 analyzes input information to edit the data flow and displays the generation condition on a display device 4. Various graphics and commands for generation of a data flow related diagram are displayed on the right of the display screen. An output part 8 stores the completely generated data flow in an external storage device 5, and the data flow related diagram is printed by a printer 6. Meanwhile, a converting part 9 generates a module related diagram indicating the control structure of the program from the generated data flow and supplies this diagram to the printer 6.
