Well, you should have eventually run into problems with DISP STAT wanting a keystroke. LIST STAT should have been used instead.

By using the _screens.forms(x) array, you do have full access from any form to the datasession and, in fact, any other property or method, on any other form. And I disagree with your comment that DataSessions are related to databases, rather than OOP. I would suggest that they are related to _neither_. You can't subclass them, you can't change their behaviour, etc. so they are clearly not OOP based. Additionally they aren't database (.DBC) related because you can have tables from multiple .DBCs, free tables, etc. in them, so they aren't related to the idea of a .DBC. Comments? /Paul
