Wouldn't this be perfect for the powerful %REPLACE BIF instead of the character by character scan?

Using <code>%REPLACE()</code>, you'd still have to locate the text to change, which would likely involve a character by character scan of some sort anyways. You could do the search using <code>%SCAN()</code>, but internally that still involves a character by character search through the string. Furthermore, a procedure involving <code>%REPLACE()</code> would almost certainly be slower since it would shift potentially a large amount of data within a character string for each replacement. Anyways, if you'd like to do some performance testing, I'm sure others would like to see the results.
