You can find the answers to these exercises in "Answers for Chapter 3" in the Appendix.

Exercise 1 [25 min]

Read the list of files in the current directory and convert the names to their full path specification. Don't use the shell or an external program to get the current directory. The File::Spec and Cwd modules, both of which come with Perl, should help. Print each path with four spaces before it and a newline after it, just like you did for Exercise 1 of Chapter 2. Can you reuse part of that answer for this problem?

Exercise 2 [35 min]

Parse the International Standard Book Number from the back of this book (0596102062). Install the Business::ISBN module from CPAN and use it to extract the country code and the publisher code from the number.
