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.
