See Appendix A for answers to the following exercises.
Several of these exercises ask you to use the test program from this chapter. You could manually type this program, taking great care to get all of the odd punctuation marks correct.[*] But you'll probably find it faster and easier to download the program and some other goodies from the O'Reilly web-site, as we mentioned in the Preface. You'll find this program under the name pattern_test.
