Kurt, I don't have the time to write the test program this second, but I am
99.99% certain that %scan is completely context-insensitive.  By that, I
mean that it reads characters regardless of what they contain, and so what
you're seeing doesn't make sense.

When I get a chance, I'll write a ten line test program, but until then,
here's a question.  Are you scanning a varying length field?  If so, did you
check the length?

In any case, I'll try to do some more specific testing later today.
