Try this

Const ForReading = 1 
Const TristateUseDefault = -2 

Set oFS = CreateObject("Scripting.FileSystemObject")
Set oFile = oFS.GetFile("yourfile.txt")
Set oStream = oFile.OpenAsTextStream(ForReading, TristateUseDefault) 
Do While Not oStream.AtEndOfStream 
   sRecord=oStream.ReadLine 
   If Substring(sRecord, 1, 1) = "6" Then
      ' do
   Else
      ' do nothing
   End If
Loop 
oStream.Close

Something like that

Dim nFileNum As Integer, sNextLine As String
nFileNum = FreeFile
Open "C:\log.txt" For Input As nFileNum
Do While Not EOF(nFileNum)
    Line Input #nFileNum, sNextLine
    If Mid(sNextLine, 1, 1) = "6" Then
         'here what you want
    End If
 Loop
 Close nFileNum
