Description translated:
> This system was one of the oldest IT systems in NAV, and ran in production for 51 years, from when the National Insurance Scheme was introduced in 1967. In January 2018, Presys was put into production, which together with Pesys became the successor to DSF. At that point, DSF was also shut down.
The system is written in PL/I.
It's like the Apollo 11 code, but for social services.
