But why do you need a global var in the DLL? IMHO (and for many programmers around the world), global var is not good, even in the application code.
Although I think that this is in part "received wisdom", dating back to some of the earliest ALGOL computers where globals were a comparatively scarce resource which couldn't be swapped with the same ease as variables on the stack or storage on the heap.
If they really were so unutterably bad, I'd like to think that the designers of Delphi would have gone to more trouble to define forms as something non-global.
So going back to the specific question, as I understand it you get a global in a DLL if you define a form in it. In practical terms it might not be immediately usable, but as an example I've used a form in a DLL as a template and copied menu entries from it to an appropriate form in the main app.
