Thanks, looking forward to see it.
I am using your ODBC library but it's slow for what I'm doing, maybe you'll
have some tips how to speed this up:
I have table with 700 records.
If buffer size is default 2048 it takes 881 seconds (14 minutes!) to update
every record using code below. If I change buffer size to 10240 same code
takes 17.68 seconds! Great imporvement but I noticed hard drive does more
work now.

I have this function to test speed:

procedure test_odbc_speed ()
    atom t1
    object sr_data
    STRING guid

    sr_data = execDirectODBC (H_Fazzt_Conn, "SELECT * FROM
SelectiveReception")
    if not sequence (sr_data) then
        odbcError (-sr_data)
        return
    end if

    puts (1, "start test\n")
    t1 = time ()
    for i = 1 to length (sr_data) do
        guid = sr_data [i] [SR_GUID]
        Void = execDirectODBC (H_Fazzt_Conn,
            "UPDATE SelectiveReception SET Ignore = 2 WHERE (GUID = '" &
guid & "')")
    end for
    ? time () - t1
end procedure
