Use the Mid() Function in a For loop to pull out each individual character:
Code:
Dim i As Long
Dim strCurrentAuth As String ' The current A, U, or blank space being looked at
For i = 0 To Len(rst("Store_Auth")) - 1 Step 1
' set variable strCurrentAuth to the character at location i in rst("Store_Auth")
strCurrentAuth = Mid(rst("Store_Auth"), i + 1, 1)
' Do your stuff here
If strCurrentAuth = "A" Then
' If the character is an A
ElseIf strCurrentAuth = "U" Then
' If the character is a U
ElseIf strCurrentAuth = " " Then
' If the character is a blank space
Else
' If any other character is encountered
End If
Next i
