I have a few, the biggest was converted to xBase++ a few years ago... it's is in daily use by about 300 QSs throughout the UK and Ireland (a bit) looking after squillions of pounds of construction contracts. That one was primarily written to manage a construction project back in '92/94!
I *think* I have just two other external Clipper systems still running, both for oil/gas service companies managing what is now called CRM - but didn't have a name when they were written! They are about 15 years old, perhaps a little older!
Most of my current stuff is VFP though, it is about as good as Clipper was way back then!
My accounts program is still in Clipper, but I print invoices through a VFP front end to it!
Regards
Griff
