APL\B5500: THE LANGUAGE AND ITS IMPLEMENTATION

Technical Report No. 70-09-04, Computer Science Group University of Washington, Seattle, Washington 98105 Septemher 1970 ABSTRACT APL'B5500 is a mUltiple-user interpretive system for a conversational programming language implemented on the Burroughs B5500 computer at the University of Washington. The language is patterned after APL\360 which is an implementation of IlIverson Notation." This paper describes the differences between the APL\360 and APL\B5500 languages. In addition, the algorithms and data structures used in the implementation of APL\B5500 are given.
