Service programs are useful when you have a library of general purpose or
related procedures that are useful in several (many) programs. They are
analogous to a DLL in windows. Directly bound modules are most useful when
they are used by a small number (one or two or ...) of programs. Modules
are like object modules which are linked to create a program.

With a service program, you can add additional procedures, or modify an
existing one, and (assuming that you don't change the interface) you only
need to maintain and recreate one object. With bound modules, you recreate
the module, and then you must relink (UPDPGM or CRTPGM) all of the programs
that use it.
