[TRNSYS-users] [TRNSYS18] forrtl: severe (66): output statement overflows records

[David BRADLEY]

Christopher,

  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.

kind regards,

  David
