A solution to the analysis problem for a class of grammars appropriate to the description of natural languages is essential to any system which involves the automatic processing of natural language inputs for purposes of man-machine communication, translation, information retrieval, or data processing. The analysis procedure for transformational grammars described in this paper was developed to explore the feasibility of using ordinary English as a computer control language.
