A question about a warning message...

::when I perform "calculate daylit_coefficient", the computer display"unable free error channel". what does it mean?

The source code attempted to open a file with a file unit zero which is the
same unit as is used to report system errors. It indicates that the variable
which defines the file unit was not set to a correct value. 

Usually this type of message does not indicate a serious problem if the application continues
to function.
