Hi Everybody Sorry, I do a misstake in the previous message. This is the correct one. I have an array compare problem: I have some array like this my @array1=(........); my @array2=(........); my @array3=(........); my @array4=(........); my @array5=(@array1,@array2); my @array6=(@array3,@array4); Then I use Array::compare to compare @array5 and @array6: my $comp = Array::Compare->new(DefFull => 1); my @differences=$comp->compare(\@array5, \@array6); I know there are differences between @array1 and @array3 and between @array2 and @array4, but in the @differences array I found only the differences between @array2 and @array4. Could some help me. Thanks in advances -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
