Controlling the Window by Operation at the PT Status Control Area

be disabled. (Even if the opening of a window is disabled, it is possible to close the
window by operation at the NT31/NT31C, or to move a window by a touch switch
operation which has “window move” function. Also, opening/closing/moving a win-
dow by operation of the window control area is always possible.)

word (word n + 3) from the beginning of the PT status control area.
