<p>PURPOSE:To ensure the simultaneous inputs through a keyboard and a pointer device by using a mail box as a common data storing area secured between a keyboard input task and a pointer device input task. CONSTITUTION:When an input key routine 10 is started, a keyboard input task II-A and a mouse input task II-B are produced in a task generating process I and work in parallel with each other in a multi-task form. If a keyboard is started, a key code is put into a mail box 33 as long as a key input exists. While an index is obtained to show a specific number of an icon where a pointer is set as long as a mouse button is pushed in case a mouse is started. Then said index is converted into a key code and put into the box 33. In a key code setting process III the key code is extracted out of the box 33 and set to a designated address.</p> |
