ABSTRACT:
A method for controlling a cursor of a one-line display device in a text writing equipment, where a text stored in a working memory of the text writing equipment can be displayed on the display device. The one-line display device is divided into three zones, in each of which a different control of the cursor is effected. In the first zone, comprising a plurality of display positions, the cursor works as a movable mark, i.e., after each cursor shift command or after each reproduce command, a cursor movement occurs with the displayed text standing still. When the cursor reaches the second zone of the display device, which is operator selectable, there occurs before each further cursor movement ordered by cursor shift commands or reproduce commands, a check to determine whether the last symbol stored in the working memory is displayed on the display. If not, a displacement of the displayed text occurs while the cursor remains stationary. If the last symbol in working memory is displayed, the cursor is moved into the third display zone comprising a plurality of display positions, where it again operates as movable mark with the displayed text stationary.
