摘要：
An information processing system comprises a display apparatus having a display screen which can be held in position of either vertical elongation or lateral elongation. The information processing system provides the operator with messages necessary for operation. By detecting the position of elongation of the display screen, data for the messages are selectively rotated so as to be always displayed uprightly on the display screen.
