Dbase, Clipper and Foxpro are early (late 80's and
beyond ) DOS based database languages and environments.
We cut our teeth on these, and could pick them
up again in a moment. Fox is still alive courtesy of Microsoft , but is not
(last we looked) well supported. Dbase is back in a windows format, and
deserves respect. None of these are, however, popular now.
Though we've been programming in these legacy
languages since 1986, it's hard to imagine getting any new work in them.
It's possible however you still have running programs written in them you'd
like translated and/ or re-written We have written literally hundred
of professional applications in these fine systems.
