<P> The INT 3 instruction is defined for use by debuggers to temporarily replace an instruction in a running program in order to set a breakpoint . Other INT instructions are encoded using two bytes . This makes them unsuitable for use in patching instructions ( which can be one byte long ) ; see SIGTRAP . </P>
