defining and using globals in an application

[Bob Sneidar]

I think you are saying there ought to be something called a stack global, that if declared there outside any script, will be available without declaring it in any of the substacks scripts. Yes? 

The reason they do things the way they do is so that you do not accidentally reference a global that was declared in some other app you are building. Let's say you have an accounting stack, and you have an address book stack. You decide to incorporate the address book stack into your accounting app instead of building a customer stack from scratch. 

In the stack script of both you have a global called vDatabase, which contains the name of the database where the data is hosted. Without this kind of scoping of variables, you could never be sure that they didn't get confused.
