Correct me if I'm wrong, (I don't have my <several necessary> Hypercard
manuals handy) but doesn't

	go to cardName
	if the result is not empty then
		-- the card does not exist
	else
		-- the card exists, have fun
	end if

work?  This also leaves you on the current card without any further
scripting if the desired card does not exist, unless I also have fallen
prey to the D-RAM shortage.
