Terry asks: > > I need to determine the maximum number of concurrent logons in a given account, Maximum? No....current number, yes...I think... If you setup a UDC file for the account(s) in question, *and* no other users/accounts use that UDC file, then number of users logged in to the account(s) at this time is: :listfile <the UDC filename>, 8 extract # users, divide by 2. I.e., when you logon, your UDC files are opened. For some reason, the account UDC files are opened twice per session (and per job?), hence the divide-by-2. YMMV, of course. -- Stan Sieler [log in to unmask] http://www.allegro.com/sieler.html
