[AccessD] Application.Run not passing my arguments declared optionally

I want some code which calls a dynamically named function and has a
dynamically listed number of arguments to do this upon re-open of a
database. So what I did was set the default form of my database to this
invisible form. In that form, on load, I check a record in a table which
should indicate the function or sub I want to call. So far I have tested
this only with one routine, and while I can call that routine, I cannot seem
to get the arguments to take hold. Basically, I get that they are missing,
regardless how I have tried to structure the function call. A simple
example:

Private Sub Form_Load()
Dim strRoutine As String
strRoutine = Nz(DLookup("Function", "Tbl2"), "")
If strRoutine <> "" Then
    'Suppose Function had value 'DropIndexes'
    Debug.Print Application.Run(strRoutine, , True)
End If


Function DropIndexes(Optional T, Optional Restarted)
Dim D As DAO.Database
Dim i As Long
'Tried to pass nothing for T and True for Restarted
Debug.print Ismissing(Restarted)

'
'Result:
'True


Based on this result I cannot even begin to explore further what I might do
if the arguments are different, listed in different order, or whatever, for
a different dynamically named routine.

Thanks if anyone can help me get the arguments to take hold.
