When buffering mode is set to 3 for optimistic buffering, I think I read that automatic record locking occurs. But do I still have to do commands like REPROCESS and RLOCK and ON ERROR to check for conflicts or does buffering mode 3 take care of all of that for me in a multi-user environment?

Thanks ahead of time for the advice. I am going to reread the network programming section and multi-user sharing chapters in my books, but I also wanted to understand it in your own words.
