The mechanism described in this article for character recognition takes advantage of existing matrix reference techniques to preserve sensitivity, under a single reference operation, to all criteria (called "rules") for which a character is recognized. This economy is gained by a new configuration of the matrix (called the "recognition matrix") and a new method for its maintenance. The recognition text (1) is a bit pattern in which each position represents a rule for which the character is recognized. An "on" bit signifies a specific action to be taken upon recognition, and the length of the recognition text is equal to the number of possible actions. A null recognition text has no bits "on" and indicates that a character is not recognized for any rule.
