There are any number of ways to extract "56" using a regular expression from
this string, and which would you would prefer depends on the general format=
of
the strings like that that you expect.
Can you describe how these strings look like?
Please reply to the list.

I think you should forget about regular expressions and use split:
my $sub = (split /\./, $val)[2];

Hi Irfan,
You can use unpack:
$val = "11.0.56.10000";
$new_val=unpack("x5 A2",$val); # skip forward 6, get 2
print $new_val # print 56;

unpack would be a poor choice if the number of digits in a field
changes. pack/unpack are meant for use in fixed field records.

That was a bad assumption on my side, I only considered the problem at
hand, thinking unpack will be faster that substr.
Thanks,
