No, currently not. It only keeps on trying if it is getting an error returned, with a time delay that gets bigger each try. Definitely need to look into error code handling. But it is a weird beast, google maps. While I'm not getting a value returned using the API from within Modo, I do get values if I use a website that uses the same API. Strange. And I hadn't exceeded the max amount of queries yet.
So far didn't manage to get a KeyboardInterrupt exception working. Ctrl+C doesn't do anything. Isn't this supported perhaps? The code should work as I added a try / except (KeyboardInterrupt, SystemExit) before entering the loop.
Thanks for your feedback, Takumi!
