 Variables Summary
 
 ■ Variables are used to store data that can change as the application runs.
   Each variable has a unique name that identifies it within its level of
   scope. See: ◄Scope Rules►
 
 ■ A group of variables that share a common name is called an array. Each
   element of an array has a unique index number (or subscript) that
   identifies it.
