PROBLEM TO BE SOLVED: To make debugging operation efficient by enabling the setting of a breakpoint with an intermediate language, step execution, and the reference to and the setting of the values of internally generated variables when debugging is performed by using a debugging device. SOLUTION: When a debugger 16 controls the execution of an object file 15, a user can give an execution control command indicating, for example, the file should be executed up to the indicated line of the list of a source file 11 to the debugger 16 to facilitate the debugging operation. Here, the debugger 16 can set a breakpoint according to line number information of an intermediate language and the program can be broken at the position corresponding to the user's indication. For the step execution, a switching means is provided which optionally switches the source program between one-line units and one-line units of the intermediate language according to a user's indication. When the program is switched to the intermediate language, internal generated variables can be referred to.
