Now you’re talking my language. I’m been involved with Pick systems since 1986. Pick doesn’t exist any more, but it’s the original “SQL” database using the ACCESS interface. Even the emulations are becoming scarce now. Our current system is jBase, and nice balance of Linux and Pick/Universe etc. Love those multi-valued, hashed databases. Lightening fast to code and develop. Our core systems are still green screen and keyboard based, but most activity is via B2B interfaces, web access and my area mobile apps. People of the other end have no idea the programs behind them started over 30 years ago, and the OS is based on a system created 50 years ago.
