Re: Another V5R1 query... Qualified DSs

 >> What's the difference between:

 >> Wouldn't they do exactly the same thing?

No not really.  In the first case the field name does not change - it can
be identical in multiple DSs.  It is referenced via qualification
CurrentRec.PhoneNo and PreviousRec.PhoneNo.

In the second case the field name is changed by sticking the prefix in
front of it e.g. PhoneNo becomes CPhoneNo and PPhoneNo.

Effectively it comes out to the same thing (effectiely two differently
named fields) until you consider that with the qualified option you can now
say that the PreviousRec DS is LIKEDS(CurrentRec) and all the fields and
their sizes and names come along for the ride!
