程序界面如图所示，当单击“求解”按钮Command1时，在列表框List1中显示所有满足条件的组合。

程序代码如下，请在划线处填上合适的代码。

Dim a(0 To 9) As Integer

Private Sub Command1_Click()

 Dim i, n, m As Integer

 For i = 123 To 333

  For n = 1 To 9

   a(n) = 0

 Next n

 s = 0

 call fenjie (i)    ‘使用call调用自定义过程,下同

 call fenjie (2 *i)

 call fenjie (3 *i)

 For m = 1 To 9

  s ={#blank#}1{#/blank#}

 Next m

  If s = 9 Then List1.AddItem i & “ ” & 2 * i & “ ” & 3 * i

 Next i

 End Sub

Sub fenjie(x As Integer)    ‘自定义过程,将3位数分解并修改对应下标元素的值

 a(x Mod 10) = 1

 {#blank#}2{#/blank#}

 a(x \ 100) = 1

End Sub

s=0

For k =3 To 1 Step-1

    If k <=1 Then x=1

    If k <=2 Then x=2

    If k <=3 Then x=3

    s=s+x

Next k

Text1. Text= Str(s)

该程序段运行后，文本框Text1中显示的内容是（  ）

Dim tmp As Integer

Dim a(1 To 10) As Integer

Private Sub Command1_Click()

  For i=2 To 10

Text1.Text = ""

For i= 1 To 5

  For j=i+1 To 6

  If s(i) + s(i) < s(j) + s(i) Then

    t= s(j): s(j)= s(i): s(i)=t

  End If

  Next j

Next i

For i=1 To 6

  Text1.Text = s(i) + Text1.Text

Next i

  If  Then

    tmp = a(i)

      For j=  To 1 Step -1    ‘依次后移

        If tmp > a(j) Then Exit For

        a(j+1)= a(j)

      Next j

          ‘插入数据

    End If

  Next i

  For i= 1 To 10

    List1.Addltem a(i)

  Next i

End Sub

要实现上述功能，方框①②③中的语句分别是（  ）
