    <p>Christopher,</p>
    <p> That error is typically the result of trying to write a big
      number into a spot in an output file that isn't formatted to be
      big enough to hold it. For instance if Fortran tries to write the
      number 9999 into an output file that has only been formatted to
      accept a 3-digit number, you'll see this error. If you are
      familiar with the process of running input files from the Visual
      Studio and the Intel compiler you can probably find the line on
      which the error is ocurring and increase the allowable size. If
      you prefer, though, you can send the project and any files needed
      to run it (as well as some guidance on what the increased
      TrnsysConstants values need to be) to your distributor and they
      can find and probably fix the spot that is causing the error.</p>
    <p>kind regards,</p>
