In this chapter, you'll learn how to use arrays—containers that can store multiple values at the same time. An array is a kind of super-variable.
You'll start by examining what arrays are and what you use them for. You'll then examine how to create them, populate them, and erase them. Along the way, you'll look at how to resize an array to make it contain more (or fewer) values, how to specify the scope for an array, and how to determine while your macro executes whether a particular variable name represents an array or a just an ordinary, single-value variable.
