to 1) I'm confused. C does not have a shell where you can type commands and have them executed directly; it's a compiled language. So is Java, but there are some approximations: BeanShell comes to mind. Maybe you could describe in more detail what you're trying to accomplish.

to 2) What is it about hash tables that you don't understand?
