Chapter 12: Working with Expressions

 

Expressions can be used in the Value property of a component, the Initial Value property of a parameter, and the Value, Initial Value, or Step Value properties of a computed field. Expressions can be a record source field, a built-in function or variable, a Java identifier, a parameter, or the result of a computed field. For the Value property of a component, the expression must be prefixed by an equal sign (=), such as =[Subtotal] + [Freight]. For all other properties the equal sign (=) is not accepted.
