>I have written a C++ DLL (thanks to Dave F) as a test and am working on how best to get various parameters to it's internal functions. Can someone supply a list of datatypes supported by the DECLARE statement? I know that INTEGER and STRING work, but FLOAT does not seem to work. When included in the DECLARE statement, it is ignored and I get the "too many arguments" error message.

VFP doesn't support FLOAT in the declaration. Have you tried either SINGLE or DOUBLE?
