VBA:

Sub Example_XRefDemandLoad()
    ' This example returns the current setting of
    ' XRefDemandLoad. It then changes the value, and finally
    ' it resets the value back to the original setting.
    
    Dim preferences As AcadPreferences
    Dim currXRefDemandLoad As Integer
    Dim constant As String
    Dim newConstant As String
    
    Set preferences = ThisDrawing.Application.preferences
    
    ' Retrieve the current XRefDemandLoad value
    currXRefDemandLoad = preferences.OpenSave.XrefDemandLoad
    constant = Choose(currXRefDemandLoad + 1, "acDemandLoadDisabled", "acDemandLoadEnabled", "acDemandLoadEnabledWithCopy")
    MsgBox "The current value for XRefDemandLoad is " & constant, vbInformation, "XRefDemandLoad Example"
    
    ' Change the value for XRefDemandLoad
    newConstant = "acDemandLoadEnabledWithCopy"
    preferences.OpenSave.XrefDemandLoad = acDemandLoadEnabledWithCopy
    MsgBox "The new value for XRefDemandLoad is " & newConstant, vbInformation, "XRefDemandLoad Example"
    
    ' Reset XRefDemandLoad to its original value
    preferences.OpenSave.XrefDemandLoad = currXRefDemandLoad
    MsgBox "The XRefDemandLoad value is reset to " & constant, vbInformation, "XRefDemandLoad Example"
End Sub
