ABSTRACT:
A display apparatus includes a document memory for storing data, a display section for displaying the data stored in a desired storage area of the document memory on a screen, and a scroll controller for designating data to be displayed on the display section and designating a cursor position to be displayed. When a cursor is located outside of a predetermined range on the screen, if a cursor-up or-down movement command is input, the displayed data is scrolled without moving the cursor position. When the cursor is located in the predetermined range on the screen, if the cursor-up or - down movement command is input, the cursor position changes in accordance with the command, and the displayed data is not scrolled. Even when the cursor is located outside of the predetermined range on the screen, if a storage area to be displayed by scrolling is not present in the document memory, or even if the storage area is present, if data to be displayed is not present on the screen, the cursor is displayed just as when located in the predetermined range.
