leetow2003, in looking over the other posts you've made on these forums it's pretty clear that you haven't got the first idea what you're doing, and don't show a desire to understand what it is your writing. At least, it's pretty clear in the sense that you fail to mention where you're getting your info or what you expect to do with it, open threads with meaningless titles, and fail to answer any direct questions. Either give people useful information, or do your own research. Otherwise you'll wear out your welcome here very quickly. As to the matter of your question: look it up. Looking at your post doesn't make it at all clear to me what you want.
