The paper describes TP Lex and Yacc, a compiler generator toolset for Turbo Pascal which is approximately compatible with the well-known UNIX utilities. TP Lex and Yacc are an independent development of the author and are freely available on the Internet. The system is widely used both for ...

Two additions to the original language, i.e., output guards and recursion have been proposed. Front end of the compiler was developed using LEX and YACC. An innovative code generator, generator based on tree pattern matching has been used to generate the back end of the compiler, which ...

Some languages also provide tools like Lex and Yacc, and you are free to use them. It is also OK if you want to design the scanner and parser by hand instead of using tools. 2 Micro Language Before we move on to the compiler design, it is necessary to have an introduction to Micro...

Names refer to either tokens or nonterminal symbols.yaccrequires token names to be declared as such. While the lexical analyzer might be included as part of the specification file, it is perhaps more in keeping with modular design to keep it as a separate file. Like the lexical analyzer, oth...
