Really  sounds  like a logic problem GT,or LT Vs GE or LE. I've  uncovered this type mistake before during  some IV & V audits, in other areas.

The  true  problem is  century transition. Once  you are  beyond "00" and the period your  company has to look back in time there is no longer any reason for a  four digit  year until 2098/99 again.

That  says you  could  go back to your original code when this  happens.

One  of the easy  ways to do this is  via the  Encapsulation methods offered  by  MS4. The  I/O  for  internal files in the DB is trapped to operate in  19xx time frame and the DB  is  backdated -28 years.  This is different then some other methods,in that, within a few hours  the entire encapsulation can be  removed form  both programs and the DB and all is back to pre-encapsulated changes. your  original tried & true code is  back  for  the balance of the century , if you wish.
