:= sets the variable named by the left parameter to the value of the right parameter and returns the value that was set. The variable named by the left parameter must already have been created with the [Variable] or [Local] tag.

The right parameter can be of any type. The value of the right parameter will always be copied into the variable and returned.

This symbol can also be used to set the value of an element from an array by using an [Array->Get] tag as the left parameter.

Note: If the parameter on the right hand side of the symbol is a negative literal it should be surrounded by parentheses. For example, ($var := (-1)).

[(Variable: 'Left_Parameter') := Right Parameter]

<?LassoScript
(Variable: 'Left_Parameter') := Right_Parameter;
?>

<?LassoScript
$Left_Parameter := Right_Parameter;
?>
