   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
