        2. Table Building Language.  A simple language by Robert
        Freiburghouse of MIT which combines user-defined actions
        into an abstract machine.  It can be used to build
        table-driven predictive parsers and code generators in the
        MULTICS Fortran compiler and several PL/I compilers,
        including VAX-11 PL/I.
