He does not need - at the time of the label creation with NEW, lblName 
gets two references; one of them is discarded by leaving the subroutine, 
but the other, held by the form (thanks to "(ME)"), remains; so the 
label is not destroyed. Kadaitcha is right - the label should have 
something to display, and show() does nothing because the Visible 
property is already true by default. Or, at least, so It should be - too 
lazy to try by myself...
