Legacy scripting language

Scripts written in the legacy scripting language represent a single or composite expression from the built-in and custom functions. By using a Function action within a test, you can enter an expression that refers to a specific function by name (built-in or custom). These expressions can be used in the Function or Decision action types, and within individual message fields to provide dynamic content. More complex expressions can refer to several functions by using a nested bracket syntax, which is familiar to programmers, for example: eq(5,abs(5.2)), which is the same as eq(5,5.2) and evaluates to "false."
