Hi Phil,
Depending on your version of Lua, you can use LUA_GLOBALSINDEX (5.1) or
the registry (5.2, see http://www.lua.org/manual/5.2/manual.html#4.5).
You can then use lua_gettable/lua_settable/lua_getfield/lua_setfield to
manipulate it. Alternatively, there is also
lua_getglobal/lua_setglobal.
Also, it's Lua, not LUA. ;)
