Load a DLL

Good morning, I'm needing to load a dll and I find nothing in Cobol for this, but I found the instructions in VB

 <DllImport("c:SATSAT.dll", CallingConvention := CallingConvention.Cdecl)> _
Public Function AtivarSAT(numeroSessao As Integer, subComando As Integer, codigoDeAtivacao As String, CNPJ As String, cUF As Integer) As IntPtr
End Function

How to do this in Cobol? And the dll is in 32bit and my OS is 64. I need to change something in my project. thank you.
