It doesn't need to mean this.  I have separated all the presentation logic for
my neural database tool into one RPG program.  This inserts 5250 attributes or
HTML or PCL escape codes into the datastream on the fly.  This one program does
the lot - it is used used for both the development and the operational
environments. With observability removed, it is less than 1Mb of code. It
generates sub-files, but I haven't used SFLCTL, etc. keywords for many years.
The screen, web page and print definitions are stored in the database along with
the user data, so if you want to change the layout, you change the database, not
the RPG.  It could easily generate XML as well if I could find a use for it.
