Maybe this will help you:

Tom Pittman wrote a beautiful implementation of Tiny Basic in assembler
years ago. It was published in Dr. Dobbs. You can find a lot of details
on his website (including a re-implementation in C):

It's pretty amazing: the parser/interpreter is written directly in
bytecodes which are interpreted by a custom-designed VM. This is /not/
like Java, mind you

I wrote one a while back.

You can have it if you can explain what you need it for, and this isn't a
class.
If you have been assigned an intepreter to write an educational exercise
then we'll be happy to help you, but just giving you the answer is false
help.
