An Interactive Computer System Using Graphical Flowchart Input An interactive computer system operational on a graphical computer terminal is described. This system was designed to demonstrate a method of programming by computer interpretation of a flowchart. The user draws a description of a sampled-data system and specifies description is transmitted to a large scale computer. The design is simulated, and a graphic representation of the processed signal is returned to the scope. A successful design may require numerous modifications of the original design. A graphical interactive system provides an environment to perform this iterative process efficiently and effectively. CACM February, 1970 Robins, M. F. Beyer, J.
