>George, that's clever and I'll certainly use it whenever appropriate (appropriate according to me). However, I see one problem. Jim Booth stated (in other words) that we must guarantee that all variables get out of scope when the application ends, in order to prevent interference in a next run application. Added _screen properties won't get out of scope, so Jim would disagree with this usage?!

Peter,

I don't disagree with any useage. I might not like it.

I have a basic belief related to breaking rules.

1. Know that there is a rule
2. Know what the rule is
3. Know what the price is for breaking the rule
4. Know that the price for NOT breaking the rule is higher than the price for breaking it

If you meet all of these criteria then by all means break the rule. If any piece is missing, well you will very likely have problems down the road by breaking the rule.
