PURPOSE: To indicates input and output between files in interactive and reusable form on the window system by storing a file with the coupling relation between application programs which have no data input/output indication screen.
CONSTITUTION: For example, when a spelling check is performed by applying desk-top publishing wherein a text editor, a spelling checker, typesetting software, a previewer, and a printer are combined, the application programs are combined on an input/output indication screen 201. In this case, a text icon and application icons on a file control screen are moved to the input/output control screen 201 and connected by coupling lines, and application software for processing and a bulb icon for input/output switching are placed between them to complete the combination. Further, the text 202 which is currently edited is connected to the spelling checker 206 through the bulb icon 204 and the output of the spelling checker 206 is connected to the text previewer 209.
