If the RPGBean is in a service program alone, then if the file changes
(unless you change an existing fields attributes) the only change should
be the addition of new getter and setter procedures.  UPDSRVPGM will
update the bindings, but existing programs won't change becuase the
procedures they use are still present and accounted for.

Also, as I mentioned in my last program, my new tool (free of course)
should alleviate a lot of the heavy lifting.

Encapsulation is an architecture decision.  I'm pretty sure I've given a
good defense and explanation of the benefits, but I'll certianly agree
that it is very difficult and time consuming to upgrade an existing
application to use Encapsulation.  The benefit is in the long term
maintenance.  I treat this approach like using /free... I use RPGBeans
for all my new development, but I wouldn't try to retrofit an existing
application unless it was really small and I had a lot of free time.
