IOW, there are situations where straight copy is bad. Limited types prevented it. Ada 95 does have a way to redefine assignment, but still has limited types for compatibility and for cases where predefined assignment would be bad but no redefined is needed. -- Wes Groleau Heroes, Heritage, and History http://freepages.genealogy.rootsweb.com/~wgroleau/
