FooAsync() calls BarAsync() BarAsync() encounters the await Task.Delay(2000); and returns an incomplete task to FooAsync(), which returns the incomplete task to its caller. Later, BarAsync() completes and returns 7 to FooAsync() which stores the 7 in variable x. FooAsync() continues running now that it has a value. Your startnumber can also be a 2 or 3 digit sequence using a field delimiter such as., ;, ,, or a mix of these. For example: 1.1.1 or 1.1:1. Automatically the last digit will increment. To increment the first digit, use: autonumber inc A. To increment the second digit, use: autonumber inc B.
