STDERR is the filehandle name for output to standard error, and the name is special in Perl (see perlvar). STERR is nothing special in Perl, although someone might have used it as the name for a filehandle.
You don't need any code to illustrate the difference because there's no difference to show. :)
Where did you see this and why do you ask?
