I've another issue on the above code:

When I run it for the first time, I'll obtain a file with the name
myfile. My issue is: the initial value of ext should be _.0_, so I
think the above script should name the output as myfile.0. Any hints
on this?

Thanks again.

My poor English. In fact, I want to know why your original code will
name the first downloaded file as myfile instead of myfile.0.
According to my understanding, it should also name the first
downloaded file as myfile.0 just as the below code does. Any hints?

Thanks again, I've seen.
