Private Sub Test(txtC() as TextBox)
        .
        .
        .
        txtC(3)=""
        .
        end sub

elsewhere in the program

        Test txtBox1()
        .
        .
        Test txtBox2()

I understand that a control array is not implemented as a normal array is
and that the above is not legal.

My question is: How can I do the equivalent?

Thanks
Cal George

P.S.

With a normal array is the correct way to pass an array Arr to Junk    
        Junk Arr()
or
        Junk Arr

Try passing the control array as an objectl

Private Sub Test(txtC as Object)
Dim i as integer
    For i = 1 to txtC.UBound
        Debug.Print txtC(i).Text
    Next i
End Sub

Test txtC()
