Functions operate on one or more arguments and return a single value. The returned value can be stored in a field, assigned to a Dialogue Manager variable, used in a calculation or other processing, or used in a selection or validation test. Functions provide a convenient way to perform certain calculations and manipulations.
You can use these functions to transform characters in order to facilitate translation between languages and code pages, or you can use them in DEFINE or COMPUTE fields to modify your data within a procedure. For more information, see the Using Functions and Functions Reference manuals.
