      Deutsch and I also designed this implementation language and programming system; it included an editor and source-language debugger. I implemented the parser, and four other people worked on the system. It was used to implement all the system software at Berkeley Computer Corporation, including the entire operating system, which had no machine language. This was rather unusual at the time.external link
