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.
