What is Service Program?

A Service Program is a collection of runnable procedures and available data items easily accessible by other ILE programs. In many respects it is similar to a subroutine library and procedure library.
A service program differs from a program in two ways:
It does not contain a program entry procedure. This means that you cannot call a service program using the CALL operation.
A service program is bound into a program or other service programs using binding by reference.

  1. In service program also we mention the list of modules. In Binding directory also we mention the list or modules (we can also mention Service program there) But when to use Service program when to use Bindng directory?
