Dear all, I'm trying to learn to use the IO::File object as a means of passing a filehandle from one function to another. In the perldoc documentation for IO::File, it gives the example: undef $fh; # automatically closes the file but in the reference that follows, it gives no indication for why this might be the case. Would this behaviour be caused by the destructor? If $fh goes out of scope, will the file be automatically closed? If not, why does undef $fh; close the file and how would I find this out in the reference manual? Thanks, PhilipThread Next
