Re: A quick question
I believe a major reputable organisation was still running some code myself and a colleague wrote in a hurry one night on a server room floor right up to 2019, we wrote the code in 1995. It was interfacing a data stream from RS485 and sending it to an AS400. I think we revised it once in that time when the data stream was moved from the RS485 network to ethernet.
During its lifecycle it was P-V and continued to run, in windows 2000 in its last incarnation, 24/7/52.
It was I think mostly VB6...
