A personal computer having an interactive all points addressable display terminal (44) and a cursor positioning device (52) is provided with a keyboard (28) for inputting alphanumeric character strings not exceeding a predetermined maximum length. Once the desired alphanumeric character string has been input, it can be selected as the current cursor character. As the selected current cursor character, the alphanumeric character string is displayed on the all points addressable display and movable by said cursor positioning device. When the alphanumeric character string is positioned at a desired location on the all points addressable display, it can be fixed in that location by reading the alphanumeric character string data into the display buffer.
