The London CPL1 compiler
George Coulouris · The Computer Journal · 1968
The CPL language has been described elsewhere, but as yet no implementations of it have been described. The authors have been concerned in the implementation of a subset of the full language, the implementation proceeding concurrently with the design of the language. Since the majority of the designers were not members of the implementation team, the choice of a subset was partly dictated by the state of the design process at the time. Some other motivations for the choice are given in Coulouris (1967). The implementation was intended to clarify some of the problems of implementing CPL, and to gain feedback information form user experience to assist in the design process. The authors believe that CPL is a powerful language for the demonstration of computing concepts, and that the implementation has therefore provided a useful teaching tool.
