Dear Monks, Try the following code for  $HASH_SIZE = 5; and  $HASH_SIZE = 10; and  $HASH_SIZE = 100;. I cannot explain the results. Can anyone please help me understand this? I am trying to test equality of contents of two hash tables. Your help is greatly appreciated, Andras Attached testcase: 
#!/usr/bin/perl
$HASH_SIZE = 100;
%hash1;
%hash2;

for ($i=0; $i < $HASH_SIZE; $i++) {
    $hash1{"$i"} = "i=$i";
}

%hash2 = %hash1;

print "\n\n%hash1\n";
foreach my $key (keys %hash1) {
    print "$key:$hash1{$key} ";
}
print "\n%hash2\n";
foreach my $key (keys %hash2) {
    print "$key:$hash2{$key} ";
}

if (%hash1 == %hash2) {
    print "\nequal\n";
} else 
{
    print "\nnon equal\n";
}

$hash2{"anotherone"} = "anotherONE";


print "\n\n%hash1\n";
foreach my $key (keys %hash1) {
    print "$key:$hash1{$key} ";
}
print "\n%hash2\n";
foreach my $key (keys %hash2) {
    print "$key:$hash2{$key} ";
}

if (%hash1 == %hash2) {
    print "\nequal\n";
} else 
{
    print "\nnon equal\n";
}
