My pathway right after was Delphi as well.
After it “ended” I contributed a tiny bit to the Harbour project but I think it came a little too late.
Sometimes I dive into old programming stuff I used to do, mostly forgotten and then get amazed how I was doing OOP, functional programming, memory safe systems programming, some form of automatic memory management, AOT compiled languages (statically linked) and now it seems everyone is kind of rediscovering what we were doing almost 40 years ago.
Clipper also had a huge array of third party libraries, I fondly remember Nanfor, Grumpfish, and SuperLib.
If you want to see some code, here's a repo of one of my Clipper projects: https://github.com/jasim/EasyAccounts
There is also The Oasis mirrors which have a large cache of Clipper code: https://harbour.github.io/the-oasis/docs/
