I originally posted this question, I know understand it.

To everyone who responded kindly I thank you.  To everyone else who
responded, I thank you too.  To the newsgroup I appologize for posting
something that is in the Frequently Asked Questions posting.  The
explanation in there is one of the best that I've read.  People might
want to look at it as several of the responses gave incorrect answers to
my problem.

To anyone who is thinking of posting to this newgroup with a question,
be very careful of your wording or else you will get many responces to
the wrong question, or just people annoyed at your ignorance.

To everyone that did answer, I'm sorry that I can send a mail reply to
you, but that is another problem I have to solve, thanks anyway.
