1. A language by M.E. Lesk for formatting tables, implemented as a preprocessor to nroff.
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.
