PROBLEM TO BE SOLVED: To dissolve defects in a conventional interpreter type system provided with a native code calling function, wherein illegal access from a native code part is possible because the execution of native codes is beyond the control of an interpreter and it is difficult to withdraw/recover the executing state of the native code part. SOLUTION: The native code called from the interpreter is executed by an emulation layer for performing emulation of actual hardware, and checking of illegal reference and management of the executing state required for withdrawal/recovery are performed by the emulation layer to dissolve the above defects.
