Summary for Week 3
Chapter 6, "Subroutines and Bugs", introduces the usage of subroutines to perform repeated tasks. Several examples teach us how to implement subroutines in our programs. The text then walks us through a basic tutorial of using the Perl debugger.
An interesting note is that only in Chapter 6 is the command "use strict;" introduced. We have been using this command in our programming up until this point though the author had not. He suggests that it is too much for beginning programmers to deal with until they have practiced some with programming basics.
