How to develop an interactive script in Unix systems

Hello, I'd like to create a script that runs interactively, here is an example of implementation:

The user is in the current directory.

Once the script started:
- If the user types 1, he set up a directory
- If the user types 0, he returns in the current directory
- If the user types s, it ends the script

I know the read but I do not know how to use it to make the interactive script.

See this for instance:
http://swoolley.org/man.cgi/read

Here is a quick explanation for then read:

Code:

---

OPTION # Lis read a line and puts in $ OPTION
in case $ OPTION
1)
 # Stuff
;;
0)
# More stuff
;;
* )
  # default stuff # Default stuff
;;
esac

---

Just search "read man 1" in this case: http://linux.die.net/man/1/read
