<p>PURPOSE:To easily correct program instructions by discriminating the double use of an output instruction based on stored contents of the storage circuit of a storage control means and displaying the address of a program memory also. CONSTITUTION:A program read means 200, an output instruction discriminating means 300, and a storage control means 400 are provided. After the program stored in the program memory is successively read out to register the double use of the output instruction in first and second storage circuits of the storage control means 400, the program is successively read out again from the program memory, and contents registered in first and second storage circuits are discriminated by a double write discriminating means 500, and the detection result is outputted to a display part or a printing part by an output means 600 if double write is detected. Thus, all storage positions of specific instructions related to double write in the program are reported to an operator, and the correction processing of double write instructions is easily performed.</p> |
