User-defined Functions
As its name implies, a user-defined function is a function that you can create based on a programming task that you want to solve. Like the pre-defined function, the value of a user-defined function is that you can write the code once and reuse it. You define user-defined functions using the FUNCTION statement. You’ll learn more about the FUNCTION statement, its syntax, and its role in relationship to other parts of the Progress program in Chapter 6.
