It sounds as if you want to wrap what you have in a loop. Perhaps you
want to do something like this:
while (my $data = <INPUT>) {
# existing code
}

With grep(), probably. It's documented in the perlfunc manpage.

You probably need chomp(), to get rid of the unwanted newline on the
input data string. Put it inside the while loop:
chomp($data);
Of course, you'll have to add code to output newline characters where
you do want line breaks.

Maybe you want reverse()?
Hope this helps!
