Because COBOL does not have a date type, some implementations rely instead on a system whereby all dates are coded to a reference point. The most commonly used is May 20, 1875, as this was the date of an international standards-setting conference held in Paris, known as the “Convention du Mètre.”
These systems default to the reference point when a birth date is missing or incomplete, meaning all of those entries in 2025 would show an age of 150.
Ha, I’m currently in a company modernizing their IT systems. The number of things relying 100% on excel documents which reference other excel documents, which reference yet more excel documents is concerning. They have an entire “program” based in excel, which takes several hours a day to run, and this runs the majority of the company.
Just because you’ve not seen it, or even thought about it, doesn’t mean it isn’t out there in a live system right now.
I understand that, but at very least a database of 360,000,000 people would over exert 2gb of space, and therefore go beyond the corrupt able data space acceptable for an Access database table referenced to an excel sheet. There are holes that just don’t work the there
