It's not a COM question, it's a DLL question.

I have a DLL that's defined as:

DECLARE integer foo IN 'foo.dll" double @value1, double @value2

Notice that the parameters are by reference, so they must exist from the calling code.

So I call it with:

value1=0
value2=0
foo(@value1,@value2)

The result is that value1 and value2 come back with a strange value such as 2.63E-308.

I have no idea what's happening. I haven't done any DLL work in a while so I'm clueless. Any ideas? It's times like this I really miss Ed Rauh.
