The report describes the continuing development of preprocessing, character-classification, and context-analysis techniques for hand-printed text, such as computer coding sheets in the FORTRAN language. We discuss preprocessing operations developed to find topological features such as the perimeter, the convex hull, concavities, enclosures, and spurs of a blackwhite quantized figure. We describe the present status of a program, TOPO 2, which classifies characters on the basis of these and other topological features. Finally, we detail the component functions of the LISP program developed to perform FORTRAN syntax analysis on a statement-by-statement basis.
