Yes, it's impossible (short of populating, say, a vector with all the possible values and then returning the vector). Enumerations are not "collections" of values, but lists of possible values, so the term "the whole enum" doesn't really make any sense. It's a bit like asking whether it's possible to return all the possible values a char can have. -- Richard Heathfield <http://www.cpax.org.uk> Email: -http://www. +rjh@ Google users: <http://www.cpax.org.uk/prg/writings/googly.php> "Usenet is a strange place" - dmr 29 July 1999
