This doesn't really make much sense, because if the output is empty,
it shouldn't display anything anyway. But I could see a case where
theoretically the output of one function is used to determine whether
or not another function is called. In that case make sure you do it
like this:
[if set {(func1)}]<(func2)>[if]
func 1 can be {( )} or [( )], but it can't be <( )>, because it is
processed after the conditionals, and thus will always appear to be
set. func2 can be any of the three, but it should be <( )> so BoltWire
doesn't even run the function. If func2 is {( )} or [( )], the
function will be run but not displayed when the conditional fails.
Timing is everything here...
Cheers,
Dan
