[Javascript] Using Shell to copy text from CMD window

Tue Sep 18 10:17:57 CDT 2007

I am attempting to use JScript to copy the text from a DOS/CMD window. 
The script works fine for a Windows application such as Notepad, but will
not work for the CMD window.  What am I missing?  I have pasted my code.

Thank you for any recommendations.
