Find client version

Let's say I have a connection made to an Oracle server.=20 Is there any way to programatically determine what=20 version of client that I'm using? I need something=20 that's either a query or a stored procedure (not the=20 Help->About pull-down menu) that will give me the=20 client's version. I tried the V$SESSION_CONNECT_INFO=20 but it seems to be showing me server version=20 information.

TIA ...Rudy
