[TRNSYS-users] Linking to the TRNSYS DLL

[Diego A. Arias]

Dear Steve,

I have created applications that modify the input file, and then call 
the TRNExe.exe. This alternative allows you to keep all the capabilities 
of TRNSYS.
Please let me know if this alternative works for you, as I can elaborate 
more on how to do that.
Best regards,

Diego
