   high-level language
   HLL
      (HLL) A programming language which provides some level of
      abstraction above assembly language.  These normally use
      statements consisting of English-like keywords such as "FOR",
      "PRINT" or "GOTO", where each statement corresponds to several
      machine language instructions.  It is much easier to program
      in a high-level language than in assembly language though
      the efficiency of execution depends on how good the compiler
      or interpreter is at optimising the program.
      Rarely, the variants "VHLL" and "MLL" are found.
