So, does each getter do a chain?  Or do you have something like....

if CustomerExists(CustNum)
  wkName = GetCustName()
  wkAddress = GetCustAddress()
endif

3. We never return the entire record and have not given this as an
option. Many hours of debate went into this at the begining of our
project and we finally came to the reailzation that this is not needed,
and if we do need everything it is not anymore work, we just call the
getters for each field as they are needed.

3.  I'd never have my DB layer return a LIKEREC/EXTFILE DS.  Instead,
it'd return a named DS like
ItemRec001 that would be defined in the copy source that included the
prototypes.  So If you add a
field, you add a new DS with the new format.  Basically like IBM's APIs
do.  Besides which, I very
rarely return the entire record.  Doing so isn't needed if you're
encapsulating properly and only
makes it to easy to break encapsulation.  The only program that really
needs most of the fields in a
file is a CRUD application for a master file or a file dump type
program.

4.  I wouldn't want to hire a programmer who couldn't get a very good
idea of what
getNextCustomerOrder() did by looking at the procedures name and how it
was being used without looking
at the code behind the procedures.
