hy all,first of all please excuse my bad english, i will try to write as correct as i can. here is the problem, i must make an parser, and maybe a small compiler for school an until now i searched a lot after a tutorial or a website where to find some documentation. as fixxxer wrote it is more easy to learn yacc and to make this "new" language. but if i must create the language in Borland Delphi 5, which is your advise? and probably i didn't understood, but fixxer can you be more exactly on who is Chomsky's?(and to read Chomsky's articles on language, semantic, syntax and description of language)thanks and best regards,
