Labview calling Compaq Visual Fortran DLL

[kingsguo]

Dear all,

I am using Labview to call a Compaq Viusal Fortran (V.6.6)DLL function. Any suggestions that will ultimately help me are highly appreciated. I had no problem to call such DLL function from Viual Basic. But I do not know how to call a DLL from Labview. Below isa DLL function I have created.

SUBROUTINE DCOTH(X,Y)
IMPLICIT NONE
!DEC$ ATTRIBUTES DLLEXPORT::DCOTH
!DEC$ ATTRIBUTES ALIAS:'DCOTH'::DCOTH
INTEGER I,N
DOUBLE PRECISION X,Y
Y=1.0D0/DTANH(X)
RETURN
END

My problem has beensolved after reading many posts in this forum. In general, I am supposed to use stdcall(WINAPI) as the calling convention.
