In the first case, %hash is still in scope within the subrotuine, and so is still visible and is used in the print statement. In the second case, %hash has not been defined by the time the print statement occurs, so won't work.
Please note that $hash and %hash are different variables in perl. If you want to access hash element A with hash reference $hash, you would use $hash->{A}. See perlref for details. Update: fixed a typo. -Mark
