ABSTRACT:
An electronic typewriter having a punctuation checking feature checks each punctuation feature as it is stored in a memory section, against a set of predetermined rules which define punctuation errors in terms of the context of the punctuation mark. If the punctuation mark does not agree with the defined rules, a suitable alarm, such as a visual and/or audible signal is given to the typist. A plurality of algorithms form the basis for sub-routines which a microprocessor can execute to determine if any of the rules are violated. The punctuation of a complete file can be checked by calling out each character in the file, from beginning to end and applying the checking procedure.
