You just forgot to copy "tostring".  It's used internally by print.
So print tries to call nil and by thus raises an error.  And because
you didn't have an _ERRORMESSAGE and _ALERT you don't see this error.

To get it working just insert:

	l.tostring = tostring		-- converts print-args to strings

and to see error messages

	l._ERRORMESSAGE = _ERRORMESSAGE	-- generates error message
	l._ALERT = _ALERT		-- actually prints the message

Ciao, ET.

PS: The for statement does not need the next function.
