But I've been known to be wrong on things (lately, more often than not...) Just looked on The Google, and there's no consensus I can find. Best advice seems to be that union and difference are equal precedence so the expression is evaluated left to right. Hence it's the former :-) -- Alan McKinnon alan.mckinnon@gmail.com
