Thanks for trying to help, but you seem to have completely missed my
problem. I already know TO use lua_yield and lua_resume. I'm wondering
HOW. As for "reading the reference", I did that before I came here. It
mentions nargs and nresults, but doesn't say what they are. I tried my
best to figure it out, and tried several pieces of code. I have already
explained what I tried in detail. I think that the first missing piece
would be: "return lua_yield(L, 1)". Like I said, I can halt execution
of the script, but can't figure out how to resume it again. I've tried
putting "lua_resume(L, x)" into cont(), where x is everything
reasonable I could think of (I've treid every value between -5 and 10).
I just can't seem to resume it.

I didn't include lua_yield() in the sample code, because I couldn't be
sure that I was doing it right. Perhaps I was yielding in such a way
that I couldn't return.

As for lua_newthread(), I'll look that up.
