Claim 12

A word processor according to claim 1, wherein the frequency count means includes: (f1) means for counting the frequency of use of the word data based on the address data of the word data stored in the frequency data area and the word data corresponding to the address data in the text storage area after the address storage means completes storing the address data in the frequency data area, and for storing the frequency of use of the word data in the frequency data area adjacent the corresponding address data.

Claim 13

A word processor according to claim 1, wherein the frequency count means includes: (f2) means for erasing the address data of identical word data to keep only one of the address data of the identical word data in the frequency data area when a plurality of the address data of the identical word data exist in therein.

Claim 14

A word processor according to claim 12, wherein the frequency count means includes: (f3) means for moving up following address data toward an address where the address data has been erased by said erasing means was stored in the frequency data area.

Claim 15

A word processor according to claim 13, wherein the frequency count means includes: (f4) means for subtracting the address corresponding to the erased address data from the address stored in the following word data which is moved up to a higher address.

Claim 16

Claim 17

A word processor according to claim 1, wherein the frequency count means includes: (f6) means for displaying the word data in association with the frequency of use of the word data on a display.

Claim 18

A word processor according to claim 16, wherein the frequency count means includes: (f7) means for displaying a table of counted word data and their respective frequency data as shown in an order of frequency of use.

Claim 19
