It might yield a problem because when $log is "0" it is defined but

Jeff already pointed out your error here^^.
$LinkExtor->parse($URL);
sub links
{
($tag, %links) = @_;
new(\&link);
which should be:
new(\&links);
Please add "use strict" at the top of the script.

I'm using lwp-download from the comand line to download a PDF file
from a site, and I'm receiving an error: Use of
"uninitialized value at C:\Perl\bin/lwp-download line 171."
I also receive the same message when I'm downloading a gif or jpg
Thanks,

I /think/, under Perl, "\n" is the system newline, regardless of the OS.
Under Windows, it would still be "99\n"

If you removed the "\n" ou "\r\n"
while ( $line eq "99" ){
or
while ( $line eq "99\n" ){
or under win32
while ( $line eq "99\r\n" ){

basically it is a menu and when the user
I'd guess $line is never set before the first time it is compared to 99.
Either (1) change line 11 to:
$line = 0;
while ( $line != 99){
or (2) use a do-while loop.
do {
...
} while ( $line != 99);

An alternative way to write that:
for (sort keys %opts_hash) {
next unless defined $opts_hash
Thanks for the advice. After I posted I tried this and it worked too:
foreach (keys %opts_hash)
{
# This next line of code eliminates the "Use of uninitialized value
in
# numeric eq (==)" error when 'use warnings;' is enabled.
if (
way that will not
autovivify all the keys is:
GetOptions( \my %opts_hash,
'allTests', 'CbcDec', 'CbcEnc', 'CfbDec', 'CfbEnc', 'CtrDec',
'CtrEnc', 'EcbDec', 'EcbEnc', 'OfbDec', 'OfbEnc',

You don't need $opts_hash (you aren't using it). You can get rid of
the undef warnings by making sure that the keys in %opts_hash are used
like this:
#default values for the options
my
each (keys %opts_hash)
{
if ( $opts_hash{$_} == 0 )
{
next;
}
elsif ( $opts_hash{$_} == 1 )
{
print "$_ = $opts_hash{$_}\n";
}
}
