Hi everybody, my problrm is this: I'm using TRNSYS 15 and I have a library of types with a .dll file and 5 fortran subroutines. Every time I try to compile in fortran ambient it gives me errors. What should I do to get it working? Is it possible that the library is written for TRSYS 16 and it doesn't work on my version? Thak you Nicola
