Digital Mars - c++.windows.32-bits - Problem returning float from DLL function to VB6

I am writing a DDL to be called by VB6. I am having trouble returning a
float or double from the DLL function. My incoming parameters work fine and
I have no problem returning integers to VB. My current proficiency in C++ is
not very good, although I have done some programming in C and C++ in the
past. I am also new to Digital Mars.



Any help would be appreciated.



Thanks

DMC++ returns floats and doubles in FPU regist ST(0). If that is not where
VB6 expects them to be, that will not work.
