Lesson 1
Introduction to Perl Variables
Perl Variable Concept
This module will discuss the basic vocabulary of Perl, namely its variable types.
This will allow you to write simple scripts and, more importantly, it prepares you to go on to learn the operators and other syntax you need to really use the language effectively.
Like most languages, Perl categorizes data of different types and requires that they be represented with specific syntax.
This module will teach you about those different types of data and how to represent them.
Learning a new language is difficult, partly because you sometimes must use the language to explain the language.
There are examples in this course that use language elements that have not yet been thoroughly explained.
