一个含有 n 个元素的整数数组，如果数组两个连续元素之间差的绝对值包括了[1,n-1]之间的所有整数，则称之为一组“完美跳数”。小余制作了验证完美跳数的 VB 程序，功能如下：在文本框 Text1 中输入一组以逗号分隔且以逗号结尾的整数数组，单击“验证”按钮 Command1，在标签 Label1 中显示验证结果，运行界面如图所示。

（1）观察程序界面，具有 Caption 属性的对象有_______个。（填个数）
Private Sub Command1_Click()
Dim n As Integer, i As Integer, j As Integer
Dim a(1 To 100) As Integer, b(1 To 100) As Integer
Dim s As String, chr As String, temp As String
s = Text1．Text
i = 1: n = 0
Do While i <= Len(s)
ch = Mid(s, i, 1)
If ch >= "0" And ch <= "9" Then
temp = temp + ch
Else
n = n + 1
___________
temp = ""
End If
i = i + 1
Loop
For i = 2 To n
___________ 
Next i
For i = 1 To n - 2
For j =
If b(j) < b(j - 1) Then
t = b(j): b(j) = b(j - 1): b(j - 1) = t
End If
Next j
Next i
For i = 1 To n - 1
If b(i) <> i Then Exit For
Next i
If i = n Then Label1．Caption = "完美跳数"
Else
Label1．Caption = "非完美跳数" End Sub
