[TRNSYS-users] Exporting file

Papia,
   When you choose "Export as..." either a fortran or a C++ skeleton of a 
component should be created in the location that you specify. The extension 
will be *.for in the case of Fortran and *.cpp in the case of C++. The 
"Export as..." feature also creates workspace files that would allow you to 
compile the code into an external DLL if you have the required compiler. 
The feature then tries to launch a compiler but cannot do so if you do not 
have such a compiler installed.
Kind regards,
  David
