Shell command help

I am trying to launch an application from an Excel spreadsheet using a macro and the VB shell function. I want to be able to pass the text from a cell to the macro as a command-line argument for the application.

The solution from http://www.excelforum.com/showthread.php?t=579609 is close to what I need, but I need it to pass the actual text and have the application launch using the text as an argument.

I appreciate any help.
