PROBLEM TO BE SOLVED: To prevent the illegal copy of a library, etc. SOLUTION: An enciphered library file L2 includes a protect code check procedure that finishes processing in an initialization step when there is contradiction two protect codes embedded into a performable program file. The enciphered library file L2 is decoded when the performable program file is prepared, and a first protect code C1 is embedded into the library file L2 (S304). The decoded library file 2 and an object file M2 are subsequently edited combinedly to prepare the performable program file (S305). After the used library file L2 is erased (S306), a second protect code C2 having a prescribed connection with the protect code C1 is further embedded into the performable library file M3 (S307).
