I remember doing a project for my CS degree in DBase III, and in my first job out of university I built a back office system for a very large UK cinema chain in Clipper. Discovering Blinker was a game changer, and Mike Schinkel's "Programming in Clipper 5" was my bible.
Oh the nostalgia. Linkers were exotic at the time. Before I discovered Blinker, I got to use Exospace that was shipped with Clipper 5.3. A lot of old goodies are still availabe at the The Oasis mirror at https://harbour.github.io/the-oasis/ftpgenrl.htm
Good to see Exospace being remembered. My brother Greg created that and a lot of other Clipper addons. He passed away a few years ago but I know me enjoyed being part of that community.
The nostalgia is real.
