CS-4 [1] is a programming language and an operating system interface. It was developed in the early 1970s at Intermetrics in Cambridge, Massachusetts. The first published manual was released in December 1973, entitled "CS-4 Language Reference Manual and Operating System Interface". [1] The document had three parts: CS-4 Base Language Capabilities; CS-4 Operating System Interface; and Overview of Full CS-4 Capabilities.
The CS-4 language, was developed for the United States Navy in the 1970s as a "language extension" to CMS-2 and as "a translator for existing CMS-2 programs". [4] It 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. [5] The language was first documented in 1973 by Miller et al., [5] and was revised in 1975 to allow "data abstractions and more powerful extension facilities". [5]
