I'm confused then. My loadString chunk is, for instance: print ("hello")

If I enter: return ("hello") then the stack does have a string - hello on it.

How do I call a C function and get return results if that doesn't work?

I'd rather not tell the user they can't just type 'print'. That seems odd to me.

Then to everything the user types, so I get the return value? If that were a lua restriction, it seems like it would be mentioned.

As a workaround, I see what you mean. But not being able to get return values is confusing me. It feels like I'm doing something wrong. If 'return "hello"' works, it feels like a C function that returns values should too.
