I recognized exactly that way back in 1995. I used to teach Clipper in the late 80s and early 90s and you could do so much with it. It's competitor was FoxPro, which was far less capable.
However, in hindsight after I quit using it I realized that Clipper developers often focused on perfecting code — myself included — whereas FoxPro developers just got shit done for the client/end-user. #fwiw
