https://en.wikipedia.org/wiki/JOVIAL Notable systems using embedded JOVIAL software include: Milstar communications satellite Advanced Cruise Missile B-52, B-1B,[14] B-2 bombers C-130, C-141, C-17 transport aircraft F-111, F-15, F-16 (prior to Block 50), F-117 fighter aircraft LANTIRN U-2 aircraft Boeing E-3 Sentry AWACS aircraft (Prior to Block 40/45) Navy Aegis cruisers Army Multiple Launch Rocket System (MLRS) Army Sikorsky UH-60 Black Hawk helicopters F100, F117, F119 jet engines NORAD air defense & control system (Hughes HME-5118ME system) NATO Air Defence Ground Environment (NADGE) system RL10 rocket engines Civil NAS (National Airspace System) Air Traffic Control APG-70, APG-71, and APG-73 airborne radar systems[15] The only way around this in a short term solution is to get use modern systems to emulate the OS environments and run the same code. That's how the banks and insurance companies updated their COBOL stuff. Same code running via emulation (Z/VM most likely) and plugging in the modern systems. That is why OS/2 was running on all the ATM machines in the 90s and up to the mid 2000s. Kike York is finally moving off of OS/2 for the subway payment system. Some of the airline ticket processing systems still think they are running on IBM/360s.
