Abstract
PURPOSE: To improve operability such as editing operation on a display device, by a method wherein, in a display device which displays letters, being different in letter width in the same width, when encounting with TAB code, a succeeding letter is displayed in a manner to make it coincide on a TAB position.
CONSTITUTION: In case a transfer data is i...(i=8) TAB, at a point of time when 8 pieces of i are transferred, the number (8) of data 1, a value (48) which is addition of a unit number (6) of i by the number of i, and contents (48) of a register 7÷10 (standard unit number) are loaded in a first address pointer 6, a horizontal position register 8, and a second address pointer 7, respectively. Then, when TAB data are transferred, a value b of the second address pointer 7 is incremented unitl it coincides with a TAB position of a TAB register 10, the value b is compared with a value (a) of the first address pointer 6, and contents of a display data buffer 3 are caused to increase and decrease until (a) is equal to b. This arranges a space SP in a display 5 so that a succeeding letter comes to a position which coincides with an actual TAB position.
