Oh once you start working with dictionaries you won=E2=80=99t want to stop. Y=
ou=E2=80=99ll wonder why you never used them in the past. They are one of th=

        <p>Hi all, Is there a way to use a kind of indirection, just
          like Dynamic strings and #, but for other type of variable, in
          particular with arrays? Let say I have 3 arrays named
          =E2=80=9CMyArray1=E2=80=9D, =E2=80=9CMyArray2=E2=80=9D and =E2=80=9C=
MyArray3=E2=80=9D. I need to use them with
          indirection, something like:</p>
        <pre>Dim Name1 As String=3D"MyArray1"
Dim Name2 As String=3D"MyArray2"
Dim Name3 As String=3D"MyArray3"
If Value=3D1
    Result=3D#Name1(0)
End If</pre>
