Not at all cost. In this case it is the two digit year that is the source of the problem and it will continue to propogate it's embedded corruption throughout the network, including systems that have been doing the correct thing all along. The *only* true fix is to eliminate the cause which means you and I would be further ahead by helping the old systems adapt so that the desease they are spreading is finally cured. I honestly see no way around that fact. The kludge doesn't address this need.

They are at best a placebo that ignores the real issue. A proper cure is needed and has been for 20 years now. Control paragraphs do nothing to solve the real problem which is the two digit year. It *MUST* die. It is the *ONLY* way.

The breakage is already there and has been for 20 years now. The proposal as it stands will effectively eliminate it and if it drags down systems with it then I would suggest it is 20 years overdue as they've been more than just a drag to the network's viability and integrity. It is the right thing to do.

Yes and no.
Life is good, Maurice
