By this operation, CPU24 compares the search words stored by RAM28 to data information and the total number of the search words are counted while the number of the search words contained prior to the address of a cursor position are calibrated. In the next step, the cursor is successively moved to a righthand direction by the keyboard 30 and, when the cursor position corresponds to the predetermined search word, the cursor word of CRT34 is displayed in a white and black reversal state.
