You'll need some kind of loop... I'm still not clear on what you're trying to accomplish.

When writing software, the first step is to think in terms of "What are my inputs, what are my outputs?" You then write processing to get from your inputs to your outputs.

What you have given is the processing, but neither the inputs nor the desired outputs. Based on that, I cannot help you because I don't know the purpose of the code you wrote, what it's supposed to do, or why it is inadequate.
