Answer 2

well u need to know some theory on computer lenguage, specific in two things: grammars and regular expresion. Yoy need to know how to write grammars. Then with the help of a parser generator you can procces your lenguage and generatate assembly code or any other lenguage u want.

if u like to code in java:
http://www.antlr.org/
Or you can use jflex (lexxer) and java cups (parser generator)

In C you can use yacc or just google for something else

In Ruby there is Racc

if you like functional leguages in haskell you can use Alex and Happy

The more sofisticated your lenguage, u need to code more.
