List Variables

Variables Array Variables

- An Array is simply a list of scalars (i.e. numbers and strings)
- List variables are denoted by the @dereferencing symbol
- The following statement assigns a three element list to the array variable @food and a two element list to the array variable @music.
  - ```
  @food  = ("apples", "pears", "eels");
```
- ```
@music = ("whistle", "flute");
```
Integer indexes can be used to reference elements of a list
The array is accessed by using indices starting from 0, and square brackets are used to specify the index. The expression
$food[2]

returns eels. (Notice that the @ has changed to a $ because eels is a scalar.)
