PROgramming in LOGic

SoftWare Interrupts (Reference: RISC, OS)

<programming> Programming in Logic or (French) Programmation en Logique. The first of the huge family of {logic programming} languages. Prolog was invented by Alain Colmerauer and Phillipe Roussel at the University of Aix-Marseille in 1971. It was first implemented 1972 in ALGOL-W. It was designed originally for natural-language processing but has become one of the most widely used languages for artificial intelligence. It is based on LUSH (or SLD) resolution {theorem proving} and unification. The first versions had no user-defined functions and no control structure other than the built-in depth-first search with backtracking. Early collaboration between Marseille and Robert Kowalski at University of Edinburgh continued until about 1975. Early implementations included C-Prolog, ESLPDPRO, Frolic, LM-Prolog, Open Prolog, SB-Prolog, {UPMAIL Tricia Prolog}. In 1998, the most common Prologs in use are Quintus Prolog, SICSTUS Prolog, LPA Prolog, {SWI Prolog}, AMZI Prolog, SNI Prolog.

<language> An extension of standard Prolog defined by Dale A. Miller and Gopalan Nadathur in 1986, in which terms are strongly typed lambda terms. Clauses are higher order hereditary Harrop formulas. The main novelties are universal quantification on goals and implication. The Prolog/Mali compiler compiles Lambda Prolog for the MALI abstract memory system.

A strongly typed Prolog-like logic programming language. 1986. It has user-defined domains. Programs are arranged in sections: DOMAINS, CLAUSES, PREDICATES, DATABASE and GOAL. It is currently known as PDC Prolog and is distributed by Prolog Development Center, Atlanta +1 404 873 1366. E-mail: <pdc@mcimail.com>.

The syntax and semantics of Prolog, a programming language, are the sets of rules that define how a Prolog program is written and how it is interpreted, respectively. The rules are laid out in ISO standard ISO/IEC 13211ISO/IEC 13211: Information technology — Programming languages — Prolog.
