How to find the loop count for while loop?

[ixlty]

hello, 

I want to find the loop counter when the while loop is running, without setting parameter for record additionally. Is there anyway possible for me?

Thanks in advance.

There is no loop counter that comes with the while loop step. You can easily add one using the Pre or Post expression fields.

Thank you. I compared with For loop and find that there is also no loop counter in itself. Therefore, I still have to set temperary parameter for loop counting.
