Ativação dos predefinidos, predefinidos de E/S e controle de fluxo no Pronus Prolog

Abstract

This report describes the implementation of the first set of built-in predicates of Pronus Prolog interpreter. The first part of this work discusses the way by which the interface between Prolog's execution and built-in predicates was implemented. It is also presented the first set of built-in predicates: operator handling predicates, term writing predicates, string handling predicates, expression evaluation predicates, control flow predicates and file I/0 predicates. The reader should refer to the report "Pronus Prolog execution environment" [Dallolio 91] in order to get a background for an easier understanding of this report.
