Need help for debugging in Visual C++ 2010 Express

Hi
I have a really long for loop which goes from 0 to 127 (has many other lines of code and multiple other loops, as well as a call to a very long function which I am trying to watch). I want to be able to single step through the first few iterations of the main for loop (0~5~10) then I want the loop to continue by itself to the 100th iteration, after which I want to be able to single step again for a few more iterations. How can I do this?
