Variables

Publish

SunSed variables are containers for storing values (data). They may hold any of SunSed supported data types (string, integer, arrays and etc.)

Creating Variables

Variables should always start with a $ sign.

The name of the variable follows the $, and it may start either with an underscore or a letter, never a number. After the first character, the remainder of the variable name may contain numbers too.

$x = 100
$_user_name = "Howl"
$x_of_200 = [200, 400, 600, 800]

NOTE: Variable names that start with a number are invalid.

# invalid variable declaration
$1 = 1
#=> ERROR

Variable names are case sensitive, meaning you may use $user, $USER, or $UsEr, however, they are treated as different variables.
