Babbage

    The structured assembly language for the General
   Electric Company 4xxx range of computers and their OS4000
   operating system.  It is strictly an assembler in that the
   generated code is relatively predictable but it can be written
   in a sufficiently structured manner, with indentation, control
   statements, function and procedure calls, to make the
   resultant source easy to read and manage.  Even with this
   visible structure however, it is important to remember that
   the assembly of the statement is done left to right.

   The British videotext system, Prestel is programmed in
   Babbage.
