A programming language for real-time systems

This paper describes a different approach to facilitating the design of efficient and reliable large scale computer programs. The direction taken is toward less rather than more abstraction, and toward using the computer most efficiently as a data processing machine. This is done by expressing the program in the form of a two-dimensional network with maximum visibility to the designer, and then converting the network automatically into efficient code. The interactive graphics terminal is a most powerful aid in accomplishing this process.
