Hello all, I want to return an array in a subroutine to form a two dimensional arrays in a main function. This is what I do: 
sub sub1{

    for $x (0 .. 100){
    $array[$x] = 0;
    }
# omit the part for generating the array;

    return \@array;
}

####################### main part
my $index;

for ($index=0; $index<2; $index++){
    $arr_ref = &sub1($index);
    $arr[$index] = @$arr_ref;

    foreach (0 .. 100){
    print "$arr[$index][$_]\n";
    }
}

However, there is nothing printed out. I am not sure where I wrote it wrong. Could somebody help me? Thanks!
