Don't create a new thread with the same question.
You still haven't defined what you mean by "lines in a paragraph".
Why don't you attach a VI with some data saved in it, and point how what it is you? What is that number is for the specific example you show?
Also, why do you need this piece of information? What will you do with it? Often, knowing why you want to do something really has nothing to do with the question you asked. There might be an alternative, better way to get to whatever you goal is.
