Great zot! Once upon a long ago (like 198x to 199x) I was a Clipper programmer, and I still remember quite a bit of it. I haven't even thought about it for ages, until recently, but it appears that Clipper is resurfacing here at DBForums, so I might need to put my "Clipper hat" once again.
So, what genre of Clipper interests you? I speak all of the variants from Autumn 86 through 5.x, which of them interests you? What sort of database programming are you trying to do using Clipper?
