I wouldn't however *recommend* this approach to locking as the user can never tell if their terminal is waiting on a lock, or just "hung" in some other odd manner, or perhaps processing a batch of something.
So it's rather a nasty trick to play on the user, to just use READU without a LOCKED clause -----Original Message----- From: Woodward, Bob <bob_woodw...@k2sports.com> To: U2 Users List <u2-users@listserver.u2ug.org> Sent: Thu, Feb 7, 2013 2:43 pm Subject: Re: [U2] Record locks (Unidata 7.2) You're exactly right. The only time you REALLY need the LOCKED clause if there is some need to change that approach. That was what I attempted to show in my first response. I guess I was a bit terse in that one, though.

Somebody will correct me if I'm wrong, but I thought that was exactly what READU did! If you don't provide a LOCKED clause, READU will "hang" and wait until the lock clears, then read and lock the record. As I say, check the docu and make sure I'm right ... I've never had to bother much with locks ...
