There are many ways to skin this cat and speed is hardly important these 
days, but I think an early exit from the loop on first failure is 
worthwhile. It certainly would be with a long string.

BTW my trick of using the string accumulator (&8100) works because the 
LENstring function put the string in there. It is only safe until the 
next string keyword and I would never actually use it.
