Purdue Compiler-Construction Tool Set
     
         (PCCTS) A highly integrated {lexical analser generator}
        and {parser generator} by Terence J. Parr ,
        Will E. Cohen and Henry G. Dietz , both
        of {Purdue University}.
     
        ANTLR (ANother Tool for Language Recognition) corresponds to
        YACC and DLG (DFA-based Lexical analyser Generator) functions
        like {LEX}.  PCCTS has many additional features which make it
        easier to use for a wide range of translation problems.  PCCTS
        {grammars} contain specifications for lexical and syntactic
        analysis with selective {backtracking} ("infinite lookahead"),
        {semantic predicates}, intermediate-form construction and
        error reporting.  Rules may employ {Extended BNF} (EBNF)
        grammar constructs and may define parameters, return values,
        and have {local variables}.
     
        Languages described in PCCTS are recognised via {LLk} parsers
        constructed in pure, human-readable, {C} code.  Selective
        backtracking is available to handle non-LL(k) constructs.
        PCCTS {parsers} may be compiled with a {C++} compiler.  PCCTS
        also includes the {SORCERER} tree parser generator.
     
        Current version: 1.10, runs under {Unix}, {MS-DOS}, {OS/2}, and
        {Macintosh} and is very portable.
