A CLASS OF TRANSFORMATION GRAMMARS IS DEFINED AND A COMPUTER PROGRAM FOR SENTENCE ANALYSIS IS DESCRIBED AND DOCUMENTED WITH RESPECT TO THIS CLASS. THE PROGRAM EXISTS IN PURE LISP FORM AND IN MIXED LISP AND IBM 7090 ASSEMBLY LANGUAGE FORM. THE PAPER CONTAINS INFORMATION TO PERMIT THE USER TO WRITE HIS OWN TRANSFORMATIONAL GRAMMAR. COMPUTER PROGRAM OPERATING DETAILS AND FORMATS ARE INCLUDED. THE PRINCIPAL DIFFERENCE BETWEEN THIS WORK ON SYNTACTIC ANALYSIS AND THAT OF OTHER GROUPS IS THAT FEW OTHER EFFORTS HAVE BEEN DIRECTED TOWARD THE ANALYSIS OF SENTENCES IN TERMS OF TRANSFORMATIONAL GRAMMAR.
