ABSTRACT:
A method of handling a fault which occurs during execution of an executable program comprises the steps of designating a first sequence of instructions of the executable program as visible and designating a second sequence of instructions of the executable program as invisible. According to this scheme, for the first visible sequence of instructions, faults are reported in a manner which designates an instruction at which the fault occurred. For the second invisible sequence of instructions, faults are reported in a manner which designates the invisible sequence of instructions as a whole. The invention permits fault handling for instructions added by a user to be performed in the same way as fault handling for built-in functions, and is usable with compiled machines.
