{{Further|Assembly language}}

Most assembly languages will have a macro instruction or an interrupt address available for the particular system to intercept events such as illegal op codes, program check, data errors, overflow, [[divide by zero]], and other such. IBM and Univac mainframes had the [[STXIT]] macro. [[Digital Equipment Corporation]] [[RT11]] systems had trap vectors for program errors, i/o interrupts, and such. [[DOS]] has certain interrupt addresses. [[Microsoft Windows]] has specific module calls to trap program errors.
