实现上述功能的VB程序如下，请回答下列问题：

Private Sub Command1_Click()

Dim a(20) As Long

Dim i As Integer, j As Integer, s As String List1.Clear

n = Val(Text1.Text)

a(1) = 1

List1.AddItem Str(a(1)) For i = 2 To n

    s = ""

    For j = Step -1  

        a(j) =    ①     

        s = s + Str(a(j))

    Next j

           ②        Next i

   max=a(1)

   For i=2 To 10

   Next i

当虚线框内的语句刚好执行完第6次后(此时循环变量i的值为7)，变量max的值是（  ）

Private Sub Command1_Click()     ‘列表框中输出 b(i)，代码略

End Sub

Private Sub Form_Load()

conn.ConnectionString="Provider=Microsoft.ACE.OLEDB.12.0;DATASource="& App.Path & "\GDP2018.accdb" conn.Open：Set myrecord.ActiveConnection = conn：myrecord.Open "GDP"

n = 0

Do While Not myrecord.EOF n = n + 1

a(n) = myrecord.Fields("2018")

b(n) = Left(myrecord.Fields("Area"), 5) & "   " & myrecord.Fields("2018") myrecord.MoveNext

Loop

conn.Close: myrecord.Close: Set myrecord = Nothing: Set conn = Nothing End Sub

下列说法不正确的是（  ）
