RE: Object authority

Mike,

I don't disagree with anything you've said.  As Rob mentioned, your original
(ok second) post read as if you don't use, nor recommend using the owned
program model.

I think you, Rob and I are on the same page.  Having QPGMR as the owner of
non-IBM objects, particular when using adopted authority, is a bad idea.
