<p>PURPOSE:To easily grasp which window has generated an error by providing a display control means to control the display means so as to flash the window under a processing at the time of data processing error generation. CONSTITUTION:When the error is generated during the data processing, an alarm sounding command is given to a buzzer, next, an error message is outputted, and it is stored into an area fixed beforehand in a picture memory 7. Then, the blinking processing of the window is executed. That is, the corre sponding window data in the memory 7 is made invalid, rewriting is executed to a video RAM 8, then, after prescribed waiting time passage, the window data of the memory 7 is made valid, and the rewriting is executed to the RAM 8. By repeating a window erasing action and a window display action, the window is blinking-displayed, thereafter, by the completion of the error correcting processing, the blinking action is canceled. Thus, by flashing the window, which window has generated the error can be easily grasped.</p> |
