Abstract

PURPOSE:To easily bracket an error by making a parameter area contain linkage information, and to easily discriminate a position of a subroutine in which an error has occured, in case when the error has occurred in the course of executing the subroutine. CONSTITUTION:When an instruction 11 for calling a subroutine A(2) is executed by one step in a main routine 1, a parameter required for executing the subroutine A is set in advance to a parameter describing part 33 of a paramete area 3, by the previsous instruction step of the instruction 11. In this state, when the instruction is executed, the head address Rn of the area 3 is designated, also a return address is inputted to the second word 32 of the area 3, an instruction 21 of linkage-on is set to the head of a called subroutine 2, and this instruction 21 is set to a linkage flag 311 of the head word 31 of an area indicated by the address Rn. In this way, an error in the subroutine A is bracketed easily, and a position where the error has occurred is discriminated.
