Service programs let you use your business logic with more flexibility.
By Joe Pluta
If you've never heard of a service program or actually worked with one, there are many fantastic introductory resources out there. We here at MC Press Online have a wide selection of them, including great articles written over the years and excellent books as well. They provide a thorough explanation of the fundamental concepts, and I recommend that you use those resources prior to beginning your journey into service program design. But if you already know the basics of service programs and have maybe even dipped your toe into the architecture of modules, binder source, and UPDSRVPGM, then you might now be asking a simple question: Why would I use a service program?
