<p>PURPOSE:To reduce the memory area in the inside of a programming device by providing a memory area registering a macro function in addition to the memory area to display a control block diagram. CONSTITUTION:A part in the same operations in control block diagrams 3, 4 is registered as a macro function 1a in a memory area 5 other than memory areas 1A, 2A to display control block diagrams 1, 2 on a display device. In drawing the control block diagram 3 or 4, as to the part of the same operation, it is drawn by having only to call the registered macro function 1a an the pattern to be displayed on the display device is simplified. As to memory areas 3A, 4A, it is drawn by having only to use a call instruction of the macro function 1a, then the memory areas 3A, 4A are reduced as the memory areas 1A, 2A.</p> |
