in reply to Re^2: increment a hex number
in thread increment a hex number

ideas?
Yes. I think it's time you showed us the code you are running, the output you are getting and the output you expect.

Try to look at this from our perspective: you are asking us how to add two numbers together. Why doesn't this work for you? 

use strict;
use warnings;

my $n = 0x30000;
$n += 0x10000;
