It would be best if you do your own homework. It is given to you so that you will learn something, think about what have been taucht. Read your text books and give it a try.

Once you have code and run into problems you can always come back here with a more specific question and the community will do its best to help you. Don't forget to post only the relevant code bits that pose the problem as a code dump is not usually helpful at all in getting someone to help/assist you.

Solution 2

If you cannot use tools like lex/yacc (or the cousins flex/bison) then you should write your own lexer and parser. It shouldn't be a daunting task, since assembly is relatively simple (you may find Crenshaw's wonderful Let's build a compiler[^], although dated, useful).
