RPG Service Program vs Include Source for Shared Subprocedures and SQL Calls

Hi All,

In the Python, Java and .Net world I usually create Python classes, jar files or DLLs to contain shared functionality.

Because most IBMi shops have an interesting mix of RPG code bases I'm trying to determine whether I should create a service program or use includes for shared functionality at a customer site.

With service programs, write once, bind and use everywhere.

With copy books, just include on-the-fly.

In the past I've leaned towards copybooks, but I'm curious what others think. I'm a little cautious of burying SQL functionality into one or more service programs.

Real-world thoughts appreciated.

Thanks

Regards,
