I am a little confused at the moment. I'm not sure if a nested do while loop will corrupt data input after conditions change.
This post isn't really a question, but more advise weather or not a nested do while loop is ever effective or, a total waste of code space.
I'm sorry if my explanation is poor.
Don't you mean "do" ?
My do statement isn't complete at the moment. My exit statements can't really execute until 'do' finished.
