Abstract : This document describes a program that analyzes two-dimensional mathematical expressions that have been input to a computer. These expressions are hand printed on a RAND Tablet/CRT console, and are processed by a character recognition program which replaces the user's input with machine-generated characters. The two-dimensional structures are converted in a linear string of characters, which is displayed at the top of the writing surface. The input expressions can be edited by the user on line. The linear string of characters can be processed by conventional compilers. (Author)
