<p>PURPOSE:To execute precisely calibration and addition such as insertion of a character by adding a control code to a character before and after an inseting position when a new character is to be inserted into a character string to which a control code such as an underline is added. CONSTITUTION:When a new character is inputted from a keyboard 23, a CPU 21 stores a character code sent from the keyboard 23 in an address of a main memory unit (MMU) 22. Subsequently, the CPU 21 reads out a control code corresponding to the character code preceding the concerned address. Then, the CPU 21 reads out a control code corresponding to the character code succeeding the concerned address. In the MMU 22, the character code and control code are stored correspondently. The CPU 21 compares the control codes corresponding to the character codes before and after the newly inserted character code. When both codes coincide with each other, the same control code as the one corresponding to the stored position of the new character code is written in the storing position of the control code. Addition of an underline, e.g. specified by the control data to the inserting character is automatically executed.</p> |
