The communication between the microprocessor CPU, the memory RAM, the ROM, the keyboard controller KBC, the printer controller PRTC, and the like is performed by the US.

FIG. 2 shows an arrangement of various keys on the keyboard KB. Here, KB1 is a key group for inputting data such as characters and numerals, and KB2 is a function key group. This function key group KB2 includes keys IS,
AS, and NS.

The key IS is a key for instructing the input of an initial value for numbering. After the key IS is pressed, the initial value can be input by a numeric key.

The key AS is a key for instructing the input of an increment value to be numbered. After the key AS is pressed, the increment value can be input by a numeric key.

The key NS is a key for instructing numbering. When the key NS is pressed, the number is displayed at the position where the cursor is currently located on the display screen of the display device CRT. As is well known, the cursor indicates the current character input position and can be moved by a cursor movement key (not shown) on the keyboard KB.
