<p>PURPOSE:To improve the responseness of screen switching by permitting the parallel running of a current display task and a new display task on the same screen at the time of switching the current screen and allowing a plotting control part to neglect a plotting command outputted from the current display task. CONSTITUTION:Both screen display tasks (a), (b) are simultaneously run until the task (b) is stopped and a plotting command inputted to the plotting control part 3 is executed. Switching to a screen alpha is generated, a window No.2 deletion command C3 is outputted from a screen switching control task (d). Although window No.1 plotting commands C5, C6, C7 for the screen alpha are successively outputted, the plotting control part 3 executes no operation for the No.2 plotting command because the window No.2 is deleted, so that data are normally plotted on the screen alpha. Thus, the screen switching method capable of improving the responseness of screen switching can be obtained.</p> |
