It was given: " For their work in the design and implementation of APL\360, setting new standards in simplicity, efficiency, reliability and response time for interactive systems." This team received the Grace Murray Hopper Award from the Association for Computing Machinery (ACM). Its design has not been described to the extent it deserves. Sharp Associates, Toronto, who was principally responsible for the supervisor. Lastly, APL\360 owes much of its superior time-sharing performance to Roger D. In 1966 he, Larry Breed and Richard Lathwell began work on the APL\360 interpreter. He was vice-president from incorporation to his retirement in 1989. Along with six other former FP employees he formed I. In December 1964 most employees of Ferranti-Packard's computer group were laid off. This compiler was part of the software package which are included in the sale of the FP6000 to International Computers and Tabulators. Braden and Breed were hired soon afterward.Īfter completion of SUBALGOL, he was hired by Ferranti-Packard to write an ALGOL 60 compiler for the FP6000. To address this problem, in December 1961, Moore was hired by Forsythe to work on the SUBALGOL compiler for the IBM 7090. To subject this community to the production-oriented system software offered by IBM, including a slow Fortran compiler and cumbersome operating system, would have moved academic computing at Stanford backward by several years. A significant body of faculty and students was now familiar with BALGOL, and the high compiling speed of the BAC was vital in an academic environment. This created great consternation in Forsythe’s office. In 1962 Stanford contracted with IBM to obtain an IBM 7090 for campus computing. įorsythe anticipated a problem as described by Bob Braden:īALGOL at Stanford outlived the B220 hardware. The result was a relocatable machine-language procedure, with a mechanism for equating its variables to variables of any BALGOL program, in just the form of the BALGOL compiler’s own machine-language library procedures (SIN, WRITE, READ, etc.). It was then compiled together with a procedure called BUTTERFLY, written by Moore. This resulted in BUTTERFLY which was described by George Forsythe:Įach grader program was written as a BALGOL-language procedure. He also spent time studying the Burroughs 220 BALGOL compiler. During this time he provided some support for Larry Breed’s card stunt system. Before graduation, he worked as an operator of the Burroughs 220 computer at Stanford. Along with his work on the programming language APL, he was also instrumental in the development of IPSANET, a private packet switching data network. Before this, he contributed to the SUBALGOL compiler at Stanford University and wrote the ALGOL 60 compiler for the Ferranti-Packard 6000 and the ICT 1900. Sharp Associates and held a senior position in the company for many years. It was given "for their work in the design and implementation of APL\360, setting new standards in simplicity, efficiency, reliability and response time for interactive systems." Moore (Novem– March 21, 2019) was the 1973 recipient (with Larry Breed and Richard Lathwell) of the Grace Murray Hopper Award from the Association for Computing Machinery (ACM).
