You will succeed,
Rezension bezieht sich auf: lex & yacc (A Nutshell handbook) (Taschenbuch)
This book will get you writing language compilers in Lex and Yacc. It is clearly written, to the point, and has a wealth of useful information.
It should be supplemented with a more theoretical work, like Aho, Sethi and Ullman's book on compilers.
