Hi,

The difference among PUBLIC and Private it is this:
- PUBLIC doesn't depend on the stack scope
- PRIVATE it depends on the stack scope

I understand the differences in general - I was just wondering whether there was any practcal differences in the context of Craig's usage. You say that PRIVATE does not, in some circumstances, hide a previously declared PUBLIC variable. Can you give an example? Does this only happen with variables explicitly declared as PUBLIC or can it fail to hide other variables that are in scope?

Thx,
