Systematics--a Non-Programming Language for Designing and Specifying Commercial Systems for Computers
C. B. B. Grindley · The Computer Journal · 1966
The paper describes a new language which provides tools and techniques for the systems analyst. The main feature of the language is that, like mathematics, it is an aid to problem solving, but, again like mathematics, it is not provided with a compiler. A short example is given showing how the analyst is enabled to construct a model of the information system he is designing independently of any computer considerations.
