Once upon a time, on a McDonald Douglas system I was doing a LIST and got a GFE. When we tried to figure out why, it turned out that the only possibility was the next record in the group that was displaying had been deleted, so it wasn't a 'real' GFE (we used to call them 'Gone For Ever'). I imagine the lock is to prevent false reporting of GFE's to people listing data......don't know for sure, just a guess.

Under what circumstances does a LIST... statement hold a lock? Certainly such a lock would not be an item-lock. If LIST actually sets group locks, those locks would only be held during the group read and would be released immediately after. I tries LIST.READU EVERY and it never shows any group locks stemming from LIST... Is there somewhere else I should be looking to see these locks? Or is this a UD thing in spite of the subject line?

This holds the number of seconds the system will wait at a 'Press any key to continue' message before releasing a held group lock. It defaults to 300: you might want to reduce that. Another option might be to set an autologout for that user. AFAIR the group lock is set by the list processor scanning the group, so anything that takes the list out of this situation will help. For example, a paragraph to DIVERT.OUT the listing and then show the final results should bypass this issue.

A user is running a paragraph from a menu. That paragraph simply LISTs the contents of a file. When there is more than one page of data to display, you get the "press any key" message. We have had situations when the person doing this LIST has walked away from the terminal and caused recordlock situations for other users. Mostly all of our READU's have LOCKED clause that gets STATUS() and reports the user number that is holding them up. In this case, I don't believe the locked clause is kicking in (I would have to further test on this not 100% sure). So, what happens is that the guy that walked away from his list starts to lockup other people. Im not sure of the inner workings here on the LIST, but I think I remember it having something to do with a group lock ? I was wondering if anyone would know if switching to the SHOW command would overcome the problem. It's kind of a hard one to test, because it doesn't happen all the time either. I thought someone with internals knowledge might shed some light on this for me.
