'''Assembly language''' (short form '''assembler''') is a [[programming language]] which is a human-readable form of the machine's basic [[object code]]. Rather than being in [[binary]] (expressed in whatever base), it instead uses mnemonics to indicate the instructions (e.g. 'ADD'), along with other fields to indicate the operands for each instruction (e.g. '[[stack pointer|SP]]').

A program called an '''assembler''' converts the [[source code]] to binary object code. Assemblers usually also provide for symbolic labels for locations, so that [[transfer-of-control instruction]]s can give their destinations symbolically; in addition to being more readable, this also means that such instructions don't need to be modified as the program is changed (chaning the addresses at which their targets reside).

A more advanced program for writing in assembler is a '''macro assembler''', which is an assembler enhanced to provide '''macros'''.
