Below is Visual Basic code that demonstrates the problem:
The (custom) Variable object has a default property of Value.  I want to
pass in the reference to the object into a subroutine by reference and have
the Value
property changed.  The value get changed in VB but not in the Script
control.

Any experience with this?

Dim scrctrl As New ScriptControl

Private Sub Command1_Click()
    Dim var As New Variable

    var.Name = "MyProp"
    var = 4

    MsgBox var

    Dim codetext As String
    codetext = "Sub MySub(x)" & vbCrLf & "x=3" & vbCrLf & "End Sub"

    scrctrl.AddCode codetext
    scrctrl.AddObject var.Name, var

    scrctrl.ExecuteStatement "MySub MyProp"
    MsgBox var
    MySub var
    MsgBox var
End Sub

Private Sub Form_Load()
    scrctrl.Language = "VBScript"
End Sub

    Sub MySub(x)
    x = 3
    End Sub
