The Subroutine Process

You may want to include several standard functions in an application that you can accommodate by defining and invoking a single ILF routine. If you define each of these standard functions using a subroutine process, you can invoke the same process at appropriate points throughout an application. By invoking the same set of statements during an event point within another process, you can save development and maintenance time, and ensure that the common function operates consistently each time it is used.

Refer to Chapter 3-12: Subroutine Processes for detailed specifications on defining these processes.
