Thanks for the clarification and explanation. I appreciate your taking the time to explain what's going on so I can better use what I see.
You have touched on one area that gives me the most heartburn... I don't know when examples are literal or placeholders. For instance, I now understand that "foo" and "bar" are what I think of as placeholders for the "real stuff" but I don't recognize things in some examples (like the word 'address') as something I need to replace with a real item. I'm hoping this is something that experience will teach me along the way. Then again, it may be the way I learn things... I learn by replicating what I see, and then tweaking the <bleep> out of it until I fully understand what the snippet does. Again, thanks! Lori In reply to Re: Re: Getting hash of CGI variables
