Creating 'zones'

My friend and I are creating this kind of text game, and we want to be able to travel around different areas with different features. But, we don't know how to do this kind of stuff.

I wanted to do something where we could make blocks of code with all the stuff for the 'zone', and we could just run it from a part of it. My friend's dad said something about subdirectories(?), but I didn't understand what he was talking about.

Cheers

Can you be a little clearer on what you are trying to do? It almost looks like your talking about classes or something.
