EXPORT vs AVars()

[jgreenb2]

I've started to fix up some old programs to be compatible with the latest firmware releases. A while back the function AVars() was added. However, I'm confused about what this actually does and how to best use it.

In my app I can declare:

Code:

EXPORT foo:="foo";

and this will create a variable that is scoped to the app. In other words I can access it from Home by either:

Code:

MyApp.foo

or simply

Code:

foo

if my current app is "MyApp".

Alternatively I can write:

Code:


foo;

function myFunc()
begin
  AVars("foo"):="foo";
end;

But the result seems the same. Why bother with AVars at all?
