Re: Record locking

My understand is that you lock a record any time you read it for update. The lock goes away automatically after the update is performed, or when the next record is read. Once it's locked, other processes can't read it for update. You can release the record yourself with the unlock op code in RPG, or you can read it with the no-lock (N) modifier on the chain or read operation, but once you've done that, you can't update it.

Last night a comment was made that startled me.  Is it possible this
statement is correct?

"If you access a physical file, even if its keyed, by its relative record
number to update it, you will never get a record lock in other programs."
