I have "borrowed" subroutines from this site (that work beautifully) that have:

ScreenUpdating = False
<code that changes the values of cells here
ScreenUpdating = True

I was wondering what setting the ScreenUpdating to false and back to true is
doing for me. I looked in Excel help (it was no help).

I would love a simple (I'm not an advanced user) explanation.
Thank you,
Judy
