Hi Benoit,

One of the problems you might run into is that the format of clipper's indexes (if they're using clipper's own dbms driver) is different from vfp's. Check if the extension is .ntx.

I don't think you can call clipper's libraries from anything else, but if you're willing to hack it, you might succeed (if you do, please tell me how it's done as it might come VERY handy for me sometime in the near future).

If they are using an index format that's compatible with vfp, I suggest you create the l2bin function in your vfp program and

index on l2bin(blablabla) to

This way you won't need to go crazy with using clipper's libs in your vfp program.

In case it helps, here are the details on l2bin():

Please let me know if I can help you more.
