Peter, 

This goes back to one of my original queries:

I have this text of a lua script:

"function main()
   print("hello")
end"


And if I lua_load it, lua puts an implied function around it, which gets
left on the stack.  So if I:

Lua_laod()
Lua_call()

It executes the implied function and not main.

As I thought (but which doesn¹t seem to be the case), I was seeing if
lua_load would register "main" in the global name space.  If so, I could
then get it on the stack and call it.

But alas, after lua_loading and looking for main, I get nil on the stack.

Any suggestions?

Thx,
Ando
