OK, here's the really, really odd thing. If I instance the DLL from VB, it works. From VFP, it doesn't. Oh well, switched over to PCOUNT() and it works everywhere then, so I guess I'll just fuggedaboudit.

>Nope should work. However, it may be a bug (and thus need reporting). I'll test something similar as an OLE server and let you know. In the meantime, try PCOUNT() and see if that works. You might also try coding something like IF PARAMETERS() = 1 and make the error the else condition and see what happens.
