Harbour is really interesting and, last time I saw it some years ago, its development was pretty active. I have already messed around a bit with Harbour and even wrote some small tools for personal use. I was pretty happy with the combination of modern capabilities with the old-school "TUI ergonomics", allowing one to render a TUI to a Win32 GDI context (they give a name to that capability, which I can't recall. It seems that there is also the possibility of rendering to X11 windows, if I'm not mistaken). I know a couple of decades-old Clipper shops which continued their development with Harbour (although they migrated from DBF files to relational databases), and their businesses are doing fairly well.
