Al,

I always considered the various field/file reference abilities to be a
rather poor substitute for a decent data dictionary. Maintaining data
type/size consistency is probably one of the most basic functions in any
data dictionary tool. Another basic function of such a tool is the
generation of SQL statements for you.

I assume that you already knew this, so you must have something else in
mind. Now I'm curious. Aside from multiple member support, what else do we
get with DDS that can't be done with SQL and a dictionary?

Regards,
