Immediate Window can not set variables

In the immediate window, I can only get the value of a variable - In VB I was used to be able to set it too.

Take the following code:

Public Sub New
    Dim a As String
    WriteLn(a) '<- I have a breakpoint on this line
End Sub

In the Immediate Window, I type ?a
And the window give nil as response

Next I type a = "somevalue"
And the window gives false as response - the variable has not been set

I would have expected that a would have the value “somevalue” after this last action.
