I came across a set of blog posts on the evaluation semantics of logo. The author of the post talks about a complicated scheme to evaluate logo tokens, especially for procedures.

However, after thinking a bit, it shouldn't be too difficult to do this using the standard recursive descent parsing to evaluate the function arguments.
