Hello Steffen, You helped me to look twice at those matters. So, it seems that variable %u (or, for what matters, even %n) indeed expands to the value as changed thru a database lookup. In fact, I now understand that I was struggling with a somewhat unexpected behavior of the prefetch database, and that I failed to correctly interpret the behaviors I was encountering. Will be a question for a next post. ;-) Thanks again, Axel
