I'm sorry for the verbose description. It appears that you're starting to get the gist. I appreciate your asking me to expound with an example. The VPN application currently have 500 lines. I'll strip it down to 50, making sure it retains functionality and post it. One of the reasons I didn't post it before, but posted "sleep(10)" to represent the application was doing something, because the program is designed to make changes to the system. But, I'm sure I'll be able to comment and have such a flow that you might be able to easily follow it just by looking at it, or, on your own, comment out the parts that makes changes. Thanks! -- L.
