Question

Are variables declared in a case statement local to that case statement –

For example, in the following code, is it safe to use z like this? Or is the compiler just placing z at the procedure scope?

         Select Case x             Case 6                 Dim z As Integer = 6             Case 7                 Dim z As Integer = 7         End Select

It’s safe to do that. You can test it by trying to compile the following:

Dim x As Integer Select Case x     Case 6         Dim z As Integer = 6     Case 7         Dim z As Integer = 7 End Select Console.Write(z) 

And noting that you’ll get a compile error.

Of course it cuts down on readability IMO. Maybe you should declare it at the beginning of the procedure anyway.
