wish of those help Do you really need a batch script? Perhaps everything you want to do can be done directly from Perl or invoked directly by Perl via its system command.
If a batch script is essential, what's wrong with creating a temporary file for the script and then executing it with system? See File::Temp, which will even delete the temporary file automatically after you are done.

will help you Rather than calling the command and reading its output, I'd suggest using IPC::Open2 or possibly IPC::Open3 and using your process B as a filter: write in, read out. At this point, you completely eliminate the shell. And, in my experience, eliminating the shell is always a good thing.
And then, to make things really simple, you run the command via IPC::Open[23], write serialised data to it (via JSON or Storable), close the write pipe (so the other side gets eof), and wait for the data. At the other end, read stdin, deserialise it, use it, and serialise your return data again. Back at the CGI server, deserialise the data you received, and away you go. This also works really well if you need to do double or triple bouncing (ssh through one machine to ssh to another).

Any of those help If I understand your problem exactly, you want to wait for the batch file to finish executing before going to the next part of your code.
You can use process.HasExited to wait for the process to finish.
code :
Dim pProces As Process = Process.Start(psi)

While Not pProces.HasExited
    System.Windows.Forms.Application.DoEvents ' if this is a windows form or console app
End While

If pProces.ExitCode = 0 Then
    ' Continue your next step here
Else
    ' Error occured while running the batch file 
End If

it fixes the issue I want to create a static variable in my module. How can I do that? Can I use our or state? , If you want to use state (which is a good idea):

will help you Edit: Its not quite clear if there are extra spaces in the original code at the start of each line causing this issue, if not, ignore the rest of this! Amon
If you try running them from the console, it will help see immediately any errors. In this case...
