Word processor

A word processor for producing text. A display data buffer retrieves, from a display font memory, display dot pattern data for inputted characters stored in a text memory and composes display dot image data which a display controller used to cause the display to display the inputted characters in an image identical to the printed out image. A cursor position memory sets and stores, each time a character or command is inputted, the present position of the cursor. Each time a character or command is inputted, a character position memory calculates and stores display character position data representing positions on the display of each of the inputted characters in each line based on the display dot image data from the display data buffer. A cursor target position calculator calculates, based on data from the cursor position memory means on the present cursor position and based on data from the character position memory means on display character positions, a cursor target position on the display each time a cursor vertical move command is inputted.
