Abstract
A programming language processing system for a computer language processing system wherein a program described in a high level programming language is translated into another program written in lower level programming language. In one embodiment of the invention, a specification of a programming language incorporates a concept of handling various basic words classified by parts-of-speech including nouns, adjectives, conjunctions, and various logic words. The program described by the programming language is converted into an internal expression form based on a sentence structure which can be converted to a binary tree. In accordance with a logic synthesis rule for term-rewriting based on a pattern collation, a logic expressed by the internal expression form is subject to conversion to a lower level program description wherein the parts-of-speech are deleted.
