<p>PURPOSE:To quickly identify a reversed area by deleting the arithmetic order identification numbers out of a screen and using different colors or different degrees of luminance to connection lines and arrows for distinction between the forward and reverse arithmetic orders. CONSTITUTION:In case the arithmetic is not carried out in the prescribed order, i.e., the arithmetic order is not coincident with the directions of arrows 14 added to the connection lines 12 and 13, the arithmetic order is reversed between an input/output signal block 11 shown by LA100, for example, and a control block 10 shown by PI. In such a case,the colors and/or degrees of luminance of the connection line 12 and/or arrows are different from those of other connection lines 13 and arrows 14 for emphasized display. Thus it is possible to obviously know that the block 11 shown by LA100 is calculated after calculation of the block 10 shown by PI.</p> |
