Scott, you beat me to it.  I looked at the scan and replace
suggestions and thought a %subst and concatenate to a varying
string would be better.  It is - it performs 5 times faster than
Mel's %scan/%replace method.

But only if the string being built up is varying.  Concatenation
to the end of a varying string is very fast.

Using %replace over and over requires a lot of extra copying of
data.
