From the 7.3 RPG programmer's guide:

Service Program Overview
A service program is a bound program (type *SRVPGM) consisting of a set of procedures that can be
called by procedures in other bound programs.

Service programs are typically used for common functions that are frequently called within an application
and across applications. For example, the ILE compilers use service programs to provide run-time
services such as math functions and input/output routines. Service programs enable reuse, simplify
maintenance, and reduce storage requirements.
