(path to perl.exe) (path to perl file)file.pl < (inputfile with path) > (outputfile with path)

example:

C:\Perl\bin\perl.exe C:\test.pl < C:\sometextfile.txt > C:\someresultfile.txt

I call this *.bat file from within VB by using the following code:

iTask = Shell(Environ$("COMSPEC") & " /c " & sPath, vbHide)
   pHandle = OpenProcess(SYNCHRONIZE, False, iTask)
   If pHandle <> 0 Then
       WaitForSingleObject pHandle, INFINITE
       CloseHandle pHandle
   End If

' sPath is the path to the bat file.
' You can do sPath = AddBackSlash(App.Path)&"batchfile.bat"
' to create the proper path in vb
