PURPOSE:To prevent the storage of incorrect execution process by adding a function of checking the adequacy of an execution process to an execution process tracing function, and stopping the storage of the execution process immediately if abnormality of the execution process is found. CONSTITUTION:When subroutines are executed normally in the order of a main routine, subroutine 1, subroutine 2- subroutine 9, the final result of an execution process information area is shown by a figure (a). If some abnromality occurs during original execution transition from the subroutine 1 to the subroutine 2 to cause transition to the middle of a subroutine 4, the execution process area is shown by a figure (b). In this case, there is not exit passing information corresponding to pieces of exit passing information 1 and 4, so the execution processing is detected as program execution abnormality. |
