History
Little is known about the CS-4 language, but it was developed for the United States Navy in the 1970s, and was an ongoing research project, which was continuing the study of extensibility and abstraction techniques to develop a requirement of the language to be simple and compact. The language was first documented in 1973 by Miller et al., and was revised in 1975 to allow "data abstractions and more powerful extension facilities".
