PURPOSE: To reexecute a target program from the same point even when state information stored in a file is reduced. CONSTITUTION: In the case of debugging a target program from a prescribed point plural times, the states of respective addresses or the like of registers and memories in a target CPU of which state is changed from an initial state when a point immediately before the prescribed point is executed at first are previously stored in a state storing file 32. At the time of executing the prescribed point and after, a flag corresponding to a resource of which state is updated out of plural flags corresponding to the addresses or the like of respective registers and memories which are stored in an updating position storing table 42 is turned on. In the case of executing debugging again from the prescribed point, the state is restored to the state obtained at the time of executing the point immediately before the prescribed point at first based upon the contents stored in the file 32 and the contents of the table 42. |
