I'm having trouble running !var! examples ad described here http://ss64.com/nt/delayedexpansion.html

Instead of the expected variable content output as the example describes, I get the literal "bang V A R bang" output, any idea?

C:\>Setlocal EnableDelayedExpansion
C:\>Set _var=first
C:\>Set _var=second& Echo %_var% !_var!
first !_var!

thanks.
