IMProved Mercury autocode

   <language> (IMP) A version of {Autocode} used to program the
   {Edinburgh Multi Access System} (EMAS), one of the first
   {operating systems} written in a {high-level language},
   apparently predating {Unix}.

   Luis Damas' {Prolog} {interpreter} in IMP for EMAS led to
   {C-Prolog}.
