Well, when you get the prompt, the debugger is ready for you to type the next command. You can type any Perl expression and it will run it and show you the result. You can also single-step your program, but if those six lines are your entire program, then it'll exit right afterwards. I can't really tell you what to type next since I don't know what you're trying to do.

There's a nice built-in help to the debugger, but if you've never used it before, perldebug is indeed the thing to read next.

The debugger is very handy to know because you can also use it as interactive Perl environment (I probably use it more for that than actual debugging). There's a very nice chapter on using it in Effective Perl Programming, one of my favorite Perl books.
