Lua doesn't support references to scalar values (numbers and strings). One 
way to emulate them is to wrap your values in tables, which are always of 
reference type. This topic has been discussed a few times before, see for 
example http://lua-users.org/lists/lua-l/2006-12/msg00370.html, References 
(as in Perl).

When searching for stuff like this, the mailinglist is also a valuable 
source. There's a search-form at http://lua-users.org/lists/lua-l/.
