Hi All,

I have a DLL (build in MS Fortran and not by me) and I'm trying to use its functions. This is what I do:

DECLARE INTEGER DLLFunction IN FORTRAN.DLL INTEGER @tnResult

Now I try to use this function (lnOK = 0 and lnResult = 0)

lnOK = DLLFunction(@lnResult)
=DLLFunction(@lnResult)

Both of the above methods trigger: Declare DLL call caused an exception. (Error 2027). The only way that seams to work is:

?DLLFunction(@lnResult)

But I don't want all the 0's on my screen. What could cause these different behaviours en how to can I fixed it??
