Subject: 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,
Richard Schoen
