NORMAL END RESTORATION SYSTEM OF PROGRAM TO BE DEBUGGED

PURPOSE:To guarantee the normal end restoration of a program to be debugged by forming an address setting part for restoring the operation of the program to be debugged to a debugging program at the end of the operation of the program to be debugged. CONSTITUTION:When a dynamic debugging utility program (DU) is transferred to a subroutine program (SUB), a RUN macroinstruction is executed to start the SUB and the contents of a branch register BR are transferred to an shunting area of a data part 2-2 in an area to be debugged. The operation is once returned to a guarantee processing part 1-2 in the DU and a returned address after the end of the SUB is loaded to a branch register (i) and stored in a shunting area 2-20. Then, the operation is returned to an execution part 2-1 of the SUB to process the SUB and then returned from the shunting area of the branch register to a correct restored address (alpha) of the DU to release the access to the program (SUB) to be debugged.
