Re: Type 80 query

["Dr.Karl-Christian Rauch" <Rauch-Muenster@xxxxxxxxxxx>]

Dear Jose,
please have a look about, whether the compiled routine (Type 80) has
been linked to the fortran-library. It looks like that this has not been done
yet. So the TRNSYS processor calls a dummy routine while parsing
your TRNSYS data deck.
