<p>When carrying out replacement of signal addresses referred to in a sequence program, before-after replacement information, which specifies the relationship between signal addresses before replacement and signal addresses after replacement in a format specifying the range of addresses involved, is stored in advance. Based on the stored before-after replacement information, all the signal addresses to be replaced are searched for in the editing target sequence program or replacement target symbol table. Replacement of a signal address found in the editing target sequence program or replacement target symbol table with a corresponding after-replacement signal address is executed in accordance with the before-after replacement information.</p> |
