PURPOSE:To make it possible to perform simply the modification work of a program by detecting instruction information from a program memory, which is read out from an instruction read circuit, and instruction information set in an instruction setter. CONSTITUTION:Program memory 1 reads out a program for the purpose of writing a prescribed program or correcting and modifying the written program. In this case, instruction information from memroy 1 which is read out from instruction read circuit 4 and instruction infromation set in instruction setter 11 are detected by detector circuit 13. As a result, the modification work of a program can be performed simply without generating always coding sheets provided with up-to-data addresses. |
