PURPOSE:To shorten the checking time for interchangeability and to reduce the file size by comparing the arithmetic data with each other with the check sum secured when the interchangeability is confirmed between two information processors. CONSTITUTION:An information processor A processes a save mode, and an information processor B processes a comparison mode. For instance, the processor A belongs to an existing system and the processor B belongs to a system whose interchangeability is tested to the processor A. The arithmetic data on both processors A and B are compared with each other with the check sum secured in order to confirm the interchangeability between both processors. Therefore the comparison subject data is reduced despite addition of an arithmetic operation to secure the check sum. As a result, the time required for check of the interchangeability between processors is shortened. At the same time, the size is also reduced for a file which saves data in a save mode. |
