Your example showed an extra layer of abstraction.  I agree, it simplifies
the interface.  It's more readable.  I'd encourage RPG programmers to
implement the technique.  For example:

If Not customerAdd(customerPointer)
  Eval errorMessage = customerErrorMessage(customerPointer)

Ok.  Extra layers of abstraction do add overhead.  You have a good point.
