Francoise - this looks great. My main concern is the use of the
characters '*' and '?' in the "condensed" names. While I understand the
short names are intended for things like table columns, they could be
used for input as well. These are common characters in pattern matching
templates, and whenever we search based on text patterns, we might want
to use a template of some sort. - Doug
