'Shell' in an ASP page

Hopefully this is a simple question. I've written an ASP page for out Intranet and need to execute a shell command on the server to process same data, the results will be displayed on a web page. How can I execute a shell command (a non-web application) on the server side via visual basic scripting in an ASP page?

Thanks Mark for your help. This works however as in a previous post the application must not have any output, mine does (which I ignore)...;(
