I can access the input values and return the corresponding output values without any problems. However, the communication with the TRNSYS Core functions somehow don’t work. Whenever I invoke some function that returns an integer value (like getMaxLabelLength()), the result is NaN. Whenever I try to invoke some function that returns characters (like getDeckFileName()), TRNSYS crashes with something like „Access violation at address XXXXX in module ‚TRNDLL.DLL‘. Write of address XXXXX.“ or with „forttrl: severe (408): fort: (18): Dummy character variable ‚GETLABEL@0‘ has length 300 which is greater than actual variable length 1“ (in case of getLabel).</div><div class=""><br class=""></div><div class="">As I read in other topics like this one, there seemed to be several issues in the TRNSYS.h header file and the library files long ago: </div><div class=""><a href="https://www.mail-archive.com/trnsys-users@engr.wisc.edu/msg00005.html" class="">https://www.mail-archive.com/trnsys-users@engr.wisc.edu/msg00005.html</a></div><div class=""><br class=""></div><div class="">However, 11 years later, is there a workaround for this problem?</div><div class=""><br class=""></div><div class="">Thanks in advance.</div><div class=""><div class="">
