Re^3: Shared variable not changing?

...the queue that resides in $mcvpservers->{$server}->[2]. Do I have to push to that reference somehow?

If that's an array reference, you probably don't want

    my @queue = $mcvpservers->{$server}->[2];
[download]

but rather

    my $queue = $mcvpservers->{$server}->[2];
    ...
    push @$queue, ...
[download]

Update: as you have it, your array ref (queue) will be assigned to the first element of @queue, but whatever you push onto @queue will be added outside of what is pointed to by the array ref. Consider

use Data::Dumper;
    
our @queue = (qw(stuff in queue));
my $server = "name";
$mcvpservers->{$server}->[2] = \@queue;
# ...

my @queue = $mcvpservers->{$server}->[2];
push @queue, "morestuff";

print Dumper \@queue;
__END__
$VAR1 = [
          [
            'stuff',
            'in',
            'queue'
          ],
          'morestuff'
        ];

I'm not sure that's the problem, but if it is, how do I write `$#queue+1` and `$#{$queue[0]}+1` with array refs instead? I want to check if the queue is empty and the length of it.	[reply] [d/l] [select]

how do I write `$#queue+1` and `$#{$queue[0]}+1` with array refs instead? `$#$queue+1 $#{$queue->[0]}+1` [download] or simply `scalar @$queue # number of elements scalar @{$queue->[0]}` [download] (you don't need the `scalar` if it's in scalar context anyway, like with `if (@$queue)` ) Presuming the first element of the referenced array holds another array ref, that is (not sure what you intend to keep there...).
