[TRNSYS-users] forrtl.error (63)

Those errors come from a "write" instruction using an incorrect format
for the number to print. It is often caused by numbers bigger than 
expected. You could for example have a line that prints the number of 
iteration that says
write(*,'(I6)') nIterations
If the number of iterations is less than 106, it will be OK. But if the 
number is greater than 106, you will get an "output conversion error" 
and stars (****) will be printed to the listing file.

You should be able to find the number that causes the problem by looking 
at the listing file. If the error comes from the TRNSYS kernel or a 
standard Type, you should report it to your distributor (please send 
them your input files)

Note that the error is not a fatal one. You can click OK and the 
simulation will continue (of course if you get one error per time step 
it is not a solution).

Kind regards,
