1. A word-processing system having a memory; character, format and control data input to the system through a keyboard with a plurality of alphanumeric and function keys depressible by an operator, and a display; in combination with at least one discrete file of editable text stored within said memory, said file containing a plurality of words, some of said words being identical to previous words in said plurality and others being differentiable relative to previous words therein; a correction buffer in said memory normally storing data entered through said keyboard and held for editing purposes, said correction buffer having a number of storage positions corresponding to a full-page of characters; address means for accessing said storage position in said correction buffer, sequence control means for producing first a cleared state of said correction buffer in response to pressing at least one of said depressible keys after processing each full-page; reading means operable subsequent to producing said cleared state and causing at least a portion of said plurality of words in the file to be read word-by-word, beginning with a first word in said full-page of characters in said correction buffer; writing means likewise responsive to producing said cleared state and operable under control of said address means to store in the correction buffer said first word read by said reading means; a first frequency-of-use count element associated with said first word and located in said correction buffer at a predetermined position relative to said first word stored therein, said writing means concomitantly entering an initial count of unity in said first frequency-of-use count element; means, including an identity output, operable for comparison thereafter of each next word successively read from said file with each word currently stored in said correction buffer, said means for comparison issuing said identity output when said next word is identical to a particular one of said currently stored words upon comparison therewith, and absence of issuance of the identity output after comparison of the next word with all words currently stored in the correction buffer indicating the next word to be a differentiable word, said writing means then storing said differentiable word in said correction buffer in association with a respective frequency-of-use count element located at said predefined position relative to the differentiable word, said writing means concomitantly entering an initial count of unity in said respective frequency-of-use count element; and incrementing means responsive to said identity output, said incrementing means augmenting the count by one in the frequency-of-use count element respectively associated with said particular one of the currently stored words and located at said predefined position relative thereto when said identity output is produced; whereby for each word in the correction buffer a count of the number of times the word is used within the full-page is maintained and a determination may be made as to whether any words stored in the correction buffer are overused.

The word processing system of claim 1, further including means for clearance of said display, a detector for sensing completion of reading said plurality of words from said file, said detector thereupon issuing a signal; magnitude means determining the relative number of counts in said respective frequency-of-use count elements, including a maximum count, said means for clearance and said magnitude means both operating in response to issuance of said signal, and means for automatically presenting in the cleared display thereafter said maximum count and the word in the correction buffer associated with the frequency-of-use count element containing the maximum count.
