<p>PURPOSE:To eliminate the nullification of input information, even in case a window displayed on a CRT is not selected, by providing a means for holding temporarily an input from a keyboard. CONSTITUTION:Unless a signal for showing the setting of an active window is applied to a buffering control part 6 by a window control means 5, holding data of a buffer memory 3 is held as it is. When the active window is selected to the window control means 5 by operating a mouse 2, the signal is applied to the buffering control part 6, and the holding data of the buffer memory 3 is inputted to a central control part 4 so as to be displayed in the active window. The central control part 4 knows a program related to the active window by the control means 5 and gives data, and also, displays a result on a CRT 7 through the control means 5. According to this constitution, the information input efficiency is improved.</p> |
