Hi Anton, AR> I think it reacts well to unset! values, eg: AR> >> set-if 'a AR> ** Script Error: set-if is missing its value argument AR> ** Near: set-if 'a AR> which is similar to how a set-word! reacts. Sorry, I wasn't clear. I meant in your climber example usage. If one of the objects has a parent value that is unset it will error out, but leave a side effect. -- Gregg
