Hi,<br><br>I found the problem about the code type564.for. In the code DATA STATEMENT part, if we delete the "CALL RCHECK(INFO,YCHECK,OCHECK)", then it works well. Or else we will get the error message "Access violation at address 10037D25 in module 'TRNDLL.DLL'. Read of address 00000003." In the TRNSYS manual chapter 8 8.3.5, an example code about how to create a new component does not include "CALL RCHECK(INFO,YCHECK,OCHECK)" in the DATA STATEMENT part. What is the function of RCHECK?<br>
<br>Thank you so much<br> <br>Best Regards!!<br>
