<programming> A word or acronym used in assembly language to represent a binary machine instruction operation code. Different processors have different instruction sets and therefore use a different set of mnemonics to represent them.
E.g. ADD, B (branch), BLT (branch if less than), SVC, MOVE, LDR (load register).
