Chapter 6. Subroutines and Bugs

In this chapter you'll extend your basic knowledge in two directions:

  • Subroutines

  • Using the Perl debugger

Subroutines are an important way to structure programs. You'll use them in Chapter 7, where you'll learn how to use randomization to simulate the mutation of DNA. The Perl debugger examines a program's behavior in "slow motion" and helps you find those pesky bugs.
