Since the last big changes to LOCK mentioned by Comet Woman, LOCK has been very stable. CometFile 11.4 has also been VERY stable.

I use LOCK in two ways.

1) LOCK a transaction file (like R2) for the duration of the program. I have a generic "who has" routine based on SNAPSHOT that will expalain to another user the who and why of the lockout. There may also be a flag in the Z1 that mostly serves for restarts.

2) LOCK a major file, set a flag in Z1, and UNLOCK the file. Programs I want to block check the flag before attempting an open. Other programs and the Reporter aren't impacted.

Haven't had a problem with a "hung" LOCK for a year or so.
