Definitely would not recommend using %Scan unless you have a very small
number to parse. Will suck up CPU like a sponge.

Let me know if you are interested.

How are you tokenizing a string without using %scan() or a home grown replacement of similar design,
while getting better performance?

As I see it, no matter what you do you have to compare each byte of the string, so the big-O of the
algorithm will always be O(n).

I can't imagine that %scan() is written that poorly, but perhaps it is.

I would expect CPU usage to hit 100% parsing lots of names simply because such an algorithm would be
CPU bound.
