\100 is interpolated as @ before the string is reversed.
You could also write that as:

Good resource.
BTW, what do Hx and Oct in the table mean?
And what's the difference between them?

Subject: RE: How does defined work?
Both Zero 0 and empty string are defined values in Perl, so if you
want to test for values other than zero or empty string; then try something
like thing:
if ($nUserId) { # so 0, 0 or will fail here

How do I distinguish between no value and false? I thought defined was
supposed to do that.
defined is true if its defined and false if it is not defined
its defined if its been given a value that is defined as '' or 0..
Try this out, uncommenting the different my $foo's

perhaps you should consider NOT printing that 285074 times? would kinda
flood the term :)

You can increment letters just like you increment numbers.
$x = a;

And the letter z incremented becomes aa.

So here is the script...

addition and subtraction routines so that $a + $b added letters instead of
