PURPOSE:To quickly and easily debug a progarm by discriminating whether the address is fixed (constant) data or variable data by data discriminating information provided on a data area of a program load module. CONSTITUTION:At the time of generating a program load module 1, data discriminating information 8 for showing whether each address 5 of a data area 6 belongs to a constant data area 9 or a variable data area 10 is added to each address 5 of the program load module 1, respectively. In this state, at the time of executing the program load module 1, erroneous write to the constant data area 9 is protected by checking the data discriminating information 8, whenever a write instruction is executed. In such a way, constant data is protected, and also, in which address 5 write to the address 5 of the constant data concerned is executed is discriminated. |
