No difference in copy and deepcopy here.  I checked.
Each record is a new copy as it is.  I was sort of suspecting that the first
one was smaller because the strings were being interned.  They are all the
same.

Yes sir, I have accepted that.  Now I am just trying to understand what is
happening.  Thank you for your assistance.
