PURPOSE:To show clearly that initialization is forgotten for security of an area in a program connection/editing mode when an action is checked, by providing a function to a connection/editing part to display a secured area by an identifier and then identifying and displaying the secured area when the connection/editing action is checked. CONSTITUTION:A program is interpreted into machine words and supplied to a connection/editing part 2 in the form of a desired module 1 to produce a load module 3. When an area security detecting part 21 detects a DS instructon during the production of the module 3, the DS instruction is sent to AND processing parts 22 and 23. Logic values 1 and 0 are supplied to a terminal of the other side of the part 22 in the check and normal modes respectively. Then a conduction mode is obtained with the logic value 1 and the DS instruction actuates a byte processing part 25. While the logic value 0 sets the part 23 under a normal state and the DS instruction is supplied to an address replacement part 26. When the part 25 is actuated, the number of bytes of an area storing area is stored in the module 3. Then the part 26 is actuated in the same way as a normal mode.
