Re: [TRNSYS-users] Step by Step

Jose,

If you have access to a FORTRAN compiler you can put use Debugging mode 
and step through each and every line of the source code.  That way you 
can watch each portion of the IAM get calculated at each and every 
timestep.  That's a powerful way to watch what's actually happening 
inside of each model.
