I came across the message at: //www.freelists.org/archives/oracle-l/10-2004/msg00462.html which contains a link to: http://www.cybcon.com/~jkstill/util/util_master.html but all I get is "Page not found". Does this document still exist? At a different URL maybe? Many thanks, Jon Knight __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
