PURPOSE:To perform the uniform processing of program rewrite even in the case of the difference in application level by comparing the execution level displayed in an execution form file and the level of program rewrite with each other and rewriting a program with one level as the unit in accordance with relations between an objective level and the execution level. CONSTITUTION:A collective ALT file is provided where old data and new data are displayed in each level of program rewrite, and the execution level displayed in the execution form file and the level of program rewrite are compared with each other, and the program is rewritten with one level as a unit in order from the level equal to the execution level of the collective LAT file accordance with relations between the objective level and the execution level. Thus, the uniform processing is performed even for systems different in application level, and rewrite from a high level to a low level is possible.
