Should i rs.close and Set rs = Nothing in each loop?

[Al Smith]

Hi,
The code below simply creates a fixed-field string from the data in a database.
It reads a list of item codes from another file for the where clause of the query.

Question:
Should I close the recordset and set it to nothing before re-setting the query with the new where clause?

It doesn't seem to matter whether I do or don't.

Thanks,
Al.

Open "d:\focus\itemcode.prn" For Input As #1
While Not EOF(1)
Line Input #1, ItemCode
Set rs = cn.Execute("Select t$item,t$desc,t$cost,t$whse,t$quan " _
& "from tiitm001 where t$item='" & ItemCode & "'")
Do Until rs.EOF = True
    FocusString = Space(80)
    Mid(FocusString, 1, 20) = rs.Fields(0).Value
    Mid(FocusString, 21, 30) = rs.Fields(1).Value
    Mid(FocusString, 51, 10) = rs.Fields(2).Value
    Mid(FocusString, 61, 10) = rs.Fields(3).Value
    Mid(FocusString, 71, 10) = rs.Fields(4).Value
    Print #2, FocusString
    rs.MoveNext
Loop
