+= 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]

(Variable: 'Left_Parameter') += Right_Parameter;

$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.

  Variable: 'Result'=10;
  $Result += 5;
  Output: $Result;
