How does that work, if the strings are literals, not LUA vars ? s = "TAG1" if s=="TAG1" then ... end <some code> if s=="TAG1" then ... end unless the lua compiler builds a stringtable of literals, it cannot know that the three "TAG1" literals are the same, eg have identical pointers.
Lua does build the string table. The 3 occurances of "TAG1" above all get mapped to the same entry. Ashwin. -- no signature is a signature.
