• NIST REFPROP is FORTRAN code compiled into a DLL (dynamically linked library).
  • Precompiled DLL (dynamically linked library) are available on windows (REFPROP.DLL for 32-bit applications, and REFPRP64.DLL for 64-bit applications), and on OSX as well.
  • The user is invited to compile their own shared library from source using the CMake-based build system at https://github.com/usnistgov/REFPROP-cmake
• No universal simple way to call a dynamic library in other environments like Excel, MATLAB, LabView, python, etc.

• python
• MATLAB
• Excel
• Labview
• C/C++
• C#
• VB, VB.NET

Users are welcome to contribute wrappers to other languages and environments, and efforts are underway to make the full REFPROP API accessible to many more languages through the use of SWIG wrappers
