PURPOSE:To generate patch files for plural revision systems with one patch file by attaching effective revision information for each system on each patch data. CONSTITUTION:A load module LM21 is loaded from an LM file 2 to a main storage 8 with a load means 5. Next, SR(system revision) stored in a SR storage means 7 is read out with a patch means 6, and the presence/absence of remaining patch data in the patch file 3 is judged. When the data remains, the patch data 31 in the file 3 is read out, also, an effective SR information readout part reads out effective SR information 32. An effective SR judging part compares the SR in the means 7 with the SR information 32, and when the SR in the means 7 remains within the range of the effective SR information 32, the patch of the data 31 is executed, and when it is outside the range, no patch is performed. Such operation is repeated over all the patch data in the file 3.
