Why are the variables not downloaded?

[LeandroA]

I am intrigued to know why the variables are loaded into memory, when the form containing them is downloaded

form1

Option Explicit

Private Sub Form_Click()
    Me.Caption = Forms.Count
    Form2.Mostrar
End Sub

from2

Option Explicit
Dim value As Long

Public Sub Mostrar()
    Debug.Print value
    value = 1
    Me.Show vbModal
End Sub

the first time value = 0 but then it is always 1
