What is the max values that can be used in 'Counter' variable?
We would like to start the counter with a 10 digit number but I think the maximum value it accepts is 999999999.
The Counter variable uses a 32 bit integer. So the max value is 2147483647. If you would like a counter with 10 digits you could concatenate two variables. If only the end of your value is increasing, the first variable could be static.
