Data Source and Decoding Functions

Data source and decoding functions search for data source records, retrieve data source records or values, and assign values based on the value of an input field.

The result of a data source function must be stored in a field. The result cannot be stored in a Dialogue Manager variable.

For many functions, the output argument can be supplied either as a field name or as a format enclosed in single quotation marks (‘). However, if a function is called from a Dialogue Manager command, this argument must always be supplied as a format. If a function is called from a Maintain Data procedure, this argument must always be supplied as a field name. For detailed information about calling a function and supplying arguments, see Accessing and Calling a Function.
