Re^2: Assign and print Hash of hashes

Dear Monk,

Thanks for the reply and suggestions. I have one doubt here. You suggested me to use a 3 argument form of open, but yours and my file open, seem to be the same. Can you please tell me, what exact difference will it make in a 3 argument and a 2 argument file open?

I'm quoting from Perl Best Practices, by Damian Conway, chapter 10, the "Open Cleanly" section. Using a three-argument `open` instead ensures that the specified opening mode can never be subverted by bizarre filenames, since the second argument now specifies only the opening mode... ...as a small side-benefit, each `open` becomes visually more explicit about the intended mode...
