程序运行时，单击按钮Commandl后弹出如图所示的错误提示。出现错误的语句是(   )

现要求编写VB程序（运行界面图所示），实现如下功能：在文本框Text1中输入一个三位数整数，单击“求解”按钮Command1，在文本框Text2中显示重新组合后的最大三位数整数。某同学按此要求编写的程序如下，其中函数max(x)用于求解最大三位数整数，但加框处代码有错，请改正。

①{#blank#}1{#/blank#}      ②{#blank#}2{#/blank#}

Function max(x As Integer) As Integer

  Dim a As Integer, b As Integer, c As Integer, t As Integer

  a = x \ 100

  b = (x \ 10) \ 10             ' ①

  c = x mod 10

  If a < b Then t = a: a = b: b = t

  If a < c Then t = a: a = c: c = t

  If b < c Then t = c: c = b: b = t

  max = c* 100 + b * 10 + a     ' ②

End Function

Private Sub Command1_Click()

     Dim n As Integer, y As Integer

     n = Val(Text1.Text)

     y = max(n)

     Text2.Text = Str(y)

End Sub

Max=-10000

For i = 1 To 10

    s = 0

    For j = i To 10

      s = s + a(j)

      If s > max Then max = s

    Next j

 Next i

已知数组a(1)到a(10)的原始数据为6，-6，8，-7，7，2，-2，-1，-2，4．程序执行后，变量max的值为（   ）

Private Sub Command1_Click()

    For i ＝ 1 To Len(s1)

      ch ＝ Mid (s1, i, 1)

      If Asc(ch) <＝ 122 And Asc(ch) >＝ 97 Then

        ch ＝Chr(Asc(ch) － 32)

      End If

      If Asc(ch) >＝ 65 And Asc(ch)<＝ 90 Then

        ch ＝ Chr(65 ＋ (Asc(ch) － 62) Mod 26)

已知大写字母A的ASCII码值为65，且小写字母的 ASCII 码为对应的大写字母的ASCII码加上32。运行上述程序，若文本框Text1 中的内容为“Text1”，单击命令按钮 Command1，则文本框Text2中将显示（  ）
