With each response i learn more. I
have only read a couple of books and started trying to build things
so i am sure there are many holes in my knowledge. Did not know
about the difference between "" and empty in relation to different
data types. Did not know about the initialize variables either. But
after reading your post I looked around and found some info on it
that said if I declare the variable  as a data type the variable will
be initialized as 0. So I asume they were initialized as 0. Thanks
for your patience of someone trying to learn.
