compiler
     
         A program that converts another program
        from some {source language} (or {programming language}) to
        {machine language} (object code).  Some compilers output
        {assembly language} which is then converted to {machine
        language} by a separate {assembler}.
     
        A compiler is distinguished from an assembler by the fact that
        each input statement does not, in general, correspond to a
        single machine instruction or fixed sequence of instructions.
        A compiler may support such features as automatic allocation
        of variables, arbitrary arithmetic expressions, control
        structures such as FOR and WHILE loops, variable {scope},
        input/ouput operations, {higher-order function}s and
        {portability} of source code.
     
        {AUTOCODER}, written in 1952, was possibly the first primitive
        compiler.  {Laning and Zierler}'s compiler, written in
        1953-1954, was possibly the first true working algebraic
        compiler.
     
        See also {byte-code compiler}, {native compiler}, {optimising
        compiler}.
