BLOCK: Interactive Block Chart Design.

A program has been developed to interactively create and modify block diagrams and pictures on a computer graphics terminal. The program, called BLOCK, runs on the VAX 11780 Master Systems Controller MSC. The program provides for the interactive entry of lines, boxes, circles, arcs, diamonds, arrows, and text using artistically styled character fronts. All entities can be inserted using different colors and varying line textures. Hard copy of the created pictures can be produced on a plotter and on a color copying system, producing both transparencies and prints. The program is accessible to all computer terminals connected to the MSC.
