FLOCHART: A Solution to the Problem of Block Diagrams

Abstract

A graphics program has been developed to aid in the creation of block diagrams. Such diagrams are useful as organization charts, process of information flow diagrams, pictographs, and in several other areas. The Monsanto system, “FLOCHART”, allows the user to describe the desired output in a simple, flexible procedural language. The language allows shapes (polygons) to be placed anywhere on the page, and allows them to be of any color, size, or angle. Definitions for shapes ranging from a circle to an ear of corn are stored in libraries which can be enhanced by the user. Shapes can be connected easily. Text is also supported. FLOCHART is a FORTRAN program built around DISSPLA and is running under CMS and MVS. The system has proven to be very easy to learn, yet powerful enough for sophisticated usage.
