Hi Hilmar,
>I don't exactly have additional information, but I think that your timeline should include more information about dBASE II, III, III PLUS, IV, and even V. Also, while I never used it, it seems to me that Clipper had an important impact in the xBASE world. Major versions of Clipper should be included
I already gathered info about dBASE and Clipper (to be checked), and I'll post it tonight (as usual!).
Regards,
Fernando
