[问题求助] 代码换位则无法正常输出

securite

如下是正常的代码

Rem MaximeSkipLineToLookFor3GB.vbs
Dim strSearch
Dim strText
Dim strFile
Dim objFSO
Dim objFile
Const ForReading=1
Const ForWriting=2
Const ForAppending=8
strFile="c:\kugou.ini"
subLook
 
Function funLookUp(strText,strSearch)
Const blnInsensitive=1
If Instr(1,strText,strSearch,blnInsensitive) Then
funLookUp=strSearch & " was found"
Else
funLookUp=strSearch & " was not found"
End If
End Function
 
Sub subLook
Dim strLine
Dim strText
Dim intLine
strSearch="[" 
Set objFSO=CreateObject("Scripting.FileSystemObject")
Set objFile=objFSO.OpenTextFile(strFile,ForReading)
 
Do Until objFile.AtEndOfStream
strText=objFile.ReadLine
strLine=funLookUp(strText,strSearch)
If InStr(strLine,"not") Then 
intLine=objFile.Line-1
WScript.Echo intLine & " not at the beginning of the ini"
Else
intLine=objFile.Line-1
Wscript.Echo intLine & " is the beginning of the ini"
objFile.Close
Exit Do
End If
Loop
WScript.Echo "Opening the file a second time..."
Set objFile=objFSO.OpenTextFile(strFile,ForReading)
Do Until objFile.AtEndOfStream
If objFile.Line < intLine Then
objFile.SkipLine
ElseIf objFile.Line=intLine Then
WScript.Echo "The beginning of the ini file is: " 
WScript.Echo objFile.ReadLine
Else
WScript.Echo "The script is over"
objFile.Close
WScript.Quit
End If
Loop
End SubCOPY

正确的输出是：
Microsoft (R) Windows Script Host Version 5.8

1 not at the beginning of the ini
2 not at the beginning of the ini
3 not at the beginning of the ini
4 not at the beginning of the ini
5 not at the beginning of the ini
6 not at the beginning of the ini
7 is the beginning of the ini
Opening the file a second time...
The beginning of the ini file is:
[ActiveTab]
The script is over

但是换一下，就是把sub函数中的第二个until循环放到外面，无法正常输出
