out of several modules so it's never one or the other. Nevertheless
collecting a number of common routines into a service program is a
design decision based on:
Maintainability - you can update or fix the service program without
having to recompile/update every program that uses it (signature values
Program size - Including a module increases the size of each program
whereas in a service program the code exists once.
Speed - If the routine is small and invoked regularly in the tight
routine you may want it included as a module.
Storage encapsulation - If the code shares variables with other modules
other than through parameters you'll probably have to include it as a
This list is by no means definitive and each reason has exceptions.
