Multiple TMemo Windows

In My MDI Application I have the need to open several
Instances of a TMemo Window. How do I refference the
different windows. Are they "Arrayed", memo[0],[1] etc?
Prefferably, I would like to refference by name somehow.
Can I give each instance a different name/label/etc?

Also, to keep only the last 100 lines of a nearly
continuous stream of text(TCP/IP news feed), I use :
 while (frmStatus.statusOut.Lines.Count > 100) do
           begin
           frmStatus.statusOut.Lines.Delete(0);
           end
The problem is that when I delete(0), the cursor position
follows. With a steady stream of input, this makes for
some pretty jumpy Reading. Can I Delete(0) without
positioning the cursor?
