Abstract: Numerical control system and method for automatically directing the movement of a machine along any prescribed path from a prepared input program containing a series of command instructions with each command represented by an array of characters defining a predetermined segment of the path expressed in terms of mathematical algorithms; the system including character recognition means, a memory section in which numerical data is stored, a data processing section, an output command data storage section and a path controller wherein the memory section is supplied with such numerical data independent of said command instructions and wherein the system operates upon such numerical data in accordance with the algorithms of the command instructions to define the coordinate dimensions for the prescribed path and in response thereto the path controller executes the commands.
