<p>PURPOSE:To executes time sequential comparison without any conflict after a year (the year 2000, for example) carrying a prescribed lower digit only by preparing an era correcting program concerning the time sequential era comparing system to execute time sequential comparison using the prescribed lower digit of the era. CONSTITUTION:An era data correction part 3 is to reload a code (such as F0-F9, for example) for the prescribed lower digit of the era in a former date data part to a code smaller than this, and an era comparison part 4 provided to compare the era. With the year carrying the prescribed digit of the era as a chance, the era data correction part 3 reloads the code (F0-F9, for example) for the prescribed lower digit of the era only in the former date data part to the code smaller than it, and the era comparison part 4 takes out the code for the prescribed lower digit of the era as the object of comparison and executes the time sequential comparison in the relation of the size.</p> |
