CPL (Programming Language)

CPL (from Combined Programming Language and Cambridge Programming Language before that) was a computer programming language developed jointly between the Mathematical Laboratory at the University of Cambridge and the University of London Computer Unit during the 1960s hence CPL gained the nickname "Cambridge Plus London". The collaborative effort was responsible for the "Combined" in the name of the language (previously, the name was Cambridge Programming Language). D. W. Barron and Christopher Strachey were involved (for others see paper). In 1963 (when the paper was published) it was currently being implemented on the Titan Computer at Cambridge and the Atlas Computer at London.
