OpenVPN variables for script (tls-verify)

[cm2702]

Hi everyone. I try to write script for option tls-verify (my OS windows 7 64bit, script on vbs).
At first i get openvpn variables in temp file then read it and compare with my client certificates database.
The problem consists in that openvpn transfer variables of the client not always.
For example:
If i make small script like this

command = "cmd.exe /c " + "set"
t = Log_Vars(Run_Program_Set(command), 1)

Function Run_Program_Set(command)
Set objShell = WScript.CreateObject("WScript.Shell")
Set objExec = objShell.Exec(command)
Run_Program_Set = objExec.StdOut.ReadAll
End Function

Function Log_Vars(LineForWrite, MakeNextLine)
Const ForWriting = 2
fldr = "C:\Windows\Temp\Variables.txt"
Dim objFSO, objTxtStream
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTxtStream = objFSO.OpenTextFile(fldr, ForWriting, true)
If MakeNextLine = 1 Then
objTxtStream.Write LineForWrite & chr(13) & chr(10)
else
objTxtStream.Write LineForWrite
End If
objTxtStream.Close
Log_Vars = "Sucsess"
End Function

In the file variables.txt will be

If I add more commands in script no matter what, all variables with zero will be gone.
I know that by default variable tls_id_0 transfer like argument, but I want compare more variables

Sorry on my english
