Your oldest in-use program...

Having just bought a new laptop, I've just been installing all the necessary apps/programs, and I've just installed Lotus 123 '97 and Word Pro '97, the only reason being that I've got a basic billing template that I've been using for ages, it works flawlessly, and I can't be bothered to transfer it into Libre Office. Oh, and it's quite fun using a bit of software that is only just one step up from MS DOS (and is therefore a tiny program).
Anyone else using stupidly out-of-date stuff?

Advertised as a 1K computer , but more of a posh calculator ,posh circa 1988.
its older than some of the engineers I work with !
I remember reading somewhere that a lot of banking systems, behind all the modern surface, are still running on scripts dating back to the 1960s or 70s, and that there's no realistic prospect of removing our reliance on them, despite their potential for problems.
The Lotus Smart Suite Disc I have installed on my PC proudly proclaims that it is suitable for Windows 95, Windows 98 and Windows NT 4.0
I'm not so sure about the 60's but a lot of the banking systems were written in COBOL that was designed in 1959 not sure when the language came into commercial use ie used by the banks.
Before I retired 2000+ I know they were looking for Cobol programmers.
Although I had moved on to more modern languages Cobol still has a place in my heart.
Still a lot of COBOL code running out there - I've never worked on banking systems but I do work on IBM mainframes in other sectors and still see it, in fact it's still well supported by the likes of IBM. If I wanted to write (for example) a high performance batch process then I'd likely turn to COBOL - if you have say a few 100K transactions or more on a batch file to process, then every millisecond can count!
Likewise some of the database management systems that originated from the 60s/70s are still around. DB2 in particular, is still widely used (of course it has been developed massively over the years). Likewise IMS, which was originally developed to support the Apollo moon landing.
10 PRINT AR5E
20 GOTO 10
...but still find it really interesting that stuff that was already around then (and before) is still being used (because it works reliably for the purpose it was designed for). I wish that some of the tech companies would take note, and try to strip down programs to their bare minimum, and stop adding in features that 99% of users will never, er, use.
