<P>PROBLEM TO BE SOLVED: To provide a program analysis device allowing a user to easily specify a subroutine related to the start of a program function to be examined from among many subroutines. Ž<P>SOLUTION: In the program analyzing method, a first procedure for using a function to be examined and a second procedure for not using the function are prepared, and the first procedure and the second procedure are performed, respectively to obtain a first execution trace and a second execution trace respectively. Next, the first execution trace is compared with the second execution trace to detect subroutine call or subroutine return corresponding to a trace section where difference between them occurs first. Then, a subroutine call edge in a diagram related to call corresponding to the detected subroutine call or subroutine return is selected. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
