I don't know if I've not found it, and I don't know if it's a question or an idea. But Wolfram Alpha would be much more valuable to me if I coul use previous results in ruther calculations (like "%" in Mathematica). If this can be done and someone show me how, this will have been a question. If it can't currently be done then it's a (strong) suggestion. Finally, if everyone throws up their hands and says "Rob's an idiot because (it's as easy as ____) (it can never be done because___), I'm willing to live with that. But I'd sure like to be able use WA in that way.
