Abstract

PURPOSE:To simplify an optional debugging job by calling an optional debugging routine out of an optional area of a program to be debugged. CONSTITUTION:A debug information register mechanism 11 is started and produces a debugging routine call information 15 based on the information pointed by the debug information 14 to register a debugging routine 16 which is called out of a program to be debugged and to control the place of a program 17 to be debugged and to call the routine 16. Then an initialization mechanism 12 is started before execution of the program 17 and buries an instruction into the program 17 based on the information 15 in order to shift the control to a routine call mechanism 13. In a debug state, the mechanism 13 is called out at a designated area and a necessary debugging process is carried out after execution of the instruction of the program 17.
