In what I'm trying to do, 6491 would turn into 20, not 2. I just want the result of adding the numbers. But, what I really want is some way of addressing all the characters in a string/number, apply some function to it that returns a number, then add those numbers up. Ideally (because this is something that's useful in golfing), it would be something really small.
And, yes, I remember TPR(0,1) and magic numbers. :-)
