Abstract

A control panel having a display for displaying selected statements from a plurality of stored statements containing one or more separate elements of alterable information; four selectively operable push-button switches; and a computer for storing the stored messages and controlling the display. The switches include left and right scroll switches and up and down-increment switches. The computer controls a cursor on the display movable left and right between one or more pre-programmed positions in each displayed statement in response to operation of the scroll switches. Each of the pre-programmed positions corresponds to one of the segments of alterable information. The scroll switches cause the computer to scroll left or right for sequentially displaying the next left or right statement. Scrolling to the next stored statement is in response to the scroll switch indicating an attempt to move the cursor left or right beyond the leftmost or rightmost pre-programmed position for the displayed statement. The computer increments up and down the segment of alterable information corresponding to the pre-programmed position to which the cursor has been moved in response to operation of the increment switches.
