I don't think you can declare variables so that they are accessible outside the file. What you can do is simulate a "Property" as used in other languages like C++ C# and Delphi. Use functions in a file that set and retrieve the state of a variable and include the file in your script. For example if your "extern" variable would be a color value you might want to have $MyColor accessible from all scripts using your routines. So you would need a function or functions to set and return its value like SetMyColor GetMyColor etc..

Not sure about .dll libraries and AutoIt3 though. COM has properties also.

Sure thing. If you find out any more details I'd appreciate a heads up. I'm not sure exactly how AutoIt handles variables. For instance in C or C++ you can have a "static" variable inside a function that doesn't go away when the function returns... and use that to store the value of Get/Set functions(at least in C, in C++ you'd just use a private or protected member variable but C doesn't have classes so you improvise.) I'm not sure exactly how to approach it in AutoIt but if you mess around with it you'll probably find out the exact mechanism.

Esp. if you have any kind of access from multiple places where the order of execution is not definite(like threads or some kind of cooperative multi-tasking functions or something) you'd want to serialize access to the variable.
