Wes,

Clipper and VFP can only co-exist under some unlikely conditions. I used Clipper for years and purchased a product called the COMIX RDD from (then) LoadStone software - the RDD provided Foxpro compatible structural indexes that work rather well with VFP. You'd know if the apps used it - you'd have matching CDX files lying about. That's hurdle number one.

Hurdle number two is the record locking mechanisms differ between Clipper and VFP. Clipper had a module that could be linked into the program that made it use VFP's locking mechanisms, that would have to be linked in as well. Another issue is that Clipper will only work with FOX2X style free tables - You're down to Character, Date, Numeric and Logical types only and FORGET the DBC.

So - on the Clipper side you'll need version 5.2 or higher, a copy of the Comix/Clipmore RDD ( from http://www.grafxsoft.com/comix.htm ) and a good protected mode linker (Blinker reccommended). If you absolutely have to marry the two, that's the way to go.

Good luck with your time travels... <g>
