String operations are used to convert a text string to something new and are mostly used in value field rules. They cannot operate directly with attributes or value fields; instead, they accept attribute functions and value field functions as parameters.
You can access string functions in the Formula Contents dialog box and in the Rule Contents dialog box. Select functions from the String list in the Operators area of the dialog box.
Before you get started ensure that the Data type is set to Text in the Value Field Properties dialog box.
