in reply to Re^2: What is the correct definition of False and Null in Perl? [non-decimal strings]
in thread What is the correct definition of False and Null in Perl?

I redid your code, dropping the quotes as: 

$a=0x10; 
++$a;
print "$a\n";

[download]

And the result was 17 (perl5.10.1 and perl5.12.2), which I think was what you wanted.

P.S. I am amazed how many good comments have come from this question and the PM answers.

Thank you
