<p>PURPOSE:To display data of more than 2 picture planes on the same picture plane without switching by a key by storing a picture plane dividing program in a control memory, and providing plural display menu resistors in an I/O controller. CONSTITUTION:Data are displayed on a CRT3 by key operation on keyboard 4 by the operator. When the key is operated so as to dividedly display the display data stored in a controller memory 6, i.e. pictures B6b and X6x, pictures B6b and X6x are stored in display menu resistors 21, 22 in an I/O controller IOC2, and the stored data 21, 22 are controlled by a CPU1 in accordance with a picture division program 61, thereby displaying the picture plane B6b on the left half of the scope of a CRT3 and the picture plane X6x on the right-half of the scope of CRT3.</p> |
