Roger D. Moore (November 16, 1939 – March 21, 2019) was the 1973 recipient (withLarry Breed andRichard Lathwell) of theGrace Murray Hopper Award from theAssociation for Computing Machinery (ACM). It was given "for their work in the design and implementation ofAPL\360, setting new standards in simplicity, efficiency, reliability and response time for interactive systems."[1]
Moore was a cofounder ofI. P. Sharp Associates and held a senior position in the company for many years. Before this, he contributed to the SUBALGOL compiler atStanford University and wrote theALGOL 60 compiler for theFerranti-Packard 6000 and theICT 1900. Along with his work on the programming languageAPL, he was also instrumental in the development ofIPSANET, a privatepacket switching data network.
Roger D. Moore was born inRedlands, California. Before graduation, he worked as an operator of the Burroughs 220 computer at Stanford. During this time he provided some support forLarry Breed’s card stunt system.[2] He also spent time studying theBurroughs 220 BALGOLcompiler. This resulted in BUTTERFLY which was described byGeorge Forsythe:
Each grader program was written as a BALGOL-language procedure. It was then compiled together with a procedure called BUTTERFLY, written by Moore. 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.).[3]
Forsythe anticipated a problem as described byBob Braden:
BALGOL at Stanford outlived the B220 hardware. In 1962 Stanford contracted with IBM to obtain anIBM 7090 for campus computing. This created great consternation in Forsythe’s office. 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. 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.[4]
To address this problem, in December 1961, Moore was hired by Forsythe to work on the SUBALGOL compiler for the IBM 7090.[5] Braden and Breed were hired soon afterward.
After completion of SUBALGOL, he was hired byFerranti-Packard to write anALGOL 60 compiler for theFP6000. This compiler was part of the software package which are included in the sale of the FP6000 toInternational Computers and Tabulators.[6]
In December 1964 most employees of Ferranti-Packard's computer group were laid off. Along with six other former FP employees he formedI. P. Sharp Associates. He was vice-president from incorporation to his retirement in 1989.
In 1966 he,Larry Breed andRichard Lathwell began work on theAPL\360interpreter.[7][8]
Lastly, APL\360 owes much of its superior time-sharing performance to Roger D. Moore, of I.P. Sharp Associates, Toronto, who was principally responsible for the supervisor. Its design has not been described to the extent it deserves.[9] This team received theGrace Murray Hopper Award from theAssociation for Computing Machinery (ACM). 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."[1]
In 1970, Moore became project leader of IPSA's speculativeDOS/360COBOL compiler project.[10][11][12] Although the compiler had satisfactory performance, the market did not accept it.
IPSA offered APLtime-sharing service starting in 1969. By 1975, the inflexibility and communication error intolerance oftime-division multiplexing were no longer tolerable. He became the chief architect of theIPSANETpacket switchingcomputer network. In 1976 this system was deployed in North America and London.[13]
In 1984, IPSA released Sharp APL for the IBM PC.[14] This package included a370emulator written by Moore.
After retiring from IPSA in early 1989, he became interested in opera and chamber music.[15] Along with attending many performances, he has supported concerts,[16][17][18][19] commissions and advanced music education.[20][21][22] He died in Toronto on March 21, 2019.[23][24]
Moore has funded the composing of many works.
