Hi,
I'm a bit confused over the Scope of Global Symbols. If I have a stack with:
global gGlobal
defined outside of all handlers
and the same in a card or control script BUT in the same Stack, is
the same "gGlobal" used in both places?
Thanks a lot
Dave
There are two aspects to scope that affect you in this case.
1. A global defined outside of all handlers (I presume you mean above
all handlers) is available to all handlers within a given object, be
it a button, card, or stack. I think you are clear about this.
2. If the same global variable is defined in multiple objects, be it
a button, card, or stack, it is the same global even if the objects
are in different stacks. Globals are environment-wide global. This is
true regardless whether a global is defined outside of all handlers
or inside a specific handler.
