+= adds the value of the right parameter to the value of the left parameter and sets the left parameter to the resulting value. The left parameter should be a variable that contains a string, decimal, or integer value.
This symbol performs mathematical addition if both parameters contain decimal or integer values. The result will be a decimal if either parameter is a decimal value.
This symbol performs string concatenation if either parameter is a string. The result is the left parameter followed by the right 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;
?>
| Required Parameters | |
|---|---|
| Left_Parameter | The variable to which the value should be added. |
| Optional Parameters | |
| Right_Parameter | The value to be added. |
To add a value to a variable:
Use the addition assignment symbol +=. The value will be added to the variable and no result will be returned to the format file. The following example adds 5 to the variable Result. The value of the variable is then displayed.
<?LassoScript
Variable: 'Result'=10;
$Result += 5;
Output: $Result;
?>
