Need Help??

It's called a version string. Any "number" with more than one decimal point is converted to the corresponding characters. This is deprecated, but all's fair in obfuscation.

There's no "IP address" type in Perl. What are you doing with the IP address? If you need a packed IP address, 1.2.3.4 will work, but the accepted way to do this is

use Socket;
$a = inet_aton("1.2.3.4");

If you want the string "1.2.3.4" then use quotation marks.

Or, better yet, what if I had a function that grabbed my current IP address (let's call it $IP) and then I changed the above to:
$string = "My current IP address is $IP\n"

Thanks in advance, I'm just trying to grasp this more fully. It is certainly a neat item to mess around with...

Also, is this discussed in any of the O'Reilly Perl books? Mine are at work right now, but I'll page through them when I go in tonight.
