StdIn, StdOut, or StdErr text stream objects.
The StdIn, StdOut, and StdErr properties and methods work when running the script with the CScript.exe host executable file only. An error is returned when run with WScript.exe. It is not necessary to close standard streams; they close automatically when the process ends. If you close a standard stream, be aware that any other pointers to that standard stream become invalid. This method is provided for compatibility with the TextStream object.
