The last time I used retry ... hmmmm... FoxBase/Xenix ERROR 108 "Lock File Header" for an append action! A VFP project I did a while back had to "special case" trap for a VBA or OCX error (and then ignore it). But on error was okay for that. In fact, subsequent coding may have cleaned it up and eliminated the necessity.

What I do remember about try/catch is that it seemed to be a substitute for something that should have been part of the coding standardse (incomplete housekeepping?). It may be helpful in large team projects where no single programmer is "totally" aware of the entire project. I work mostly alone, so I have to keep my stuff fairly simple!
