Hi All,

I was told that I shouldn't use the C format of using for (i.e. for ($i=0;$i<10;$i++) for replacing the array's elements but use perl's for/foreach command. That works fine but I need to remove some cells/elements from an array, how do it using for/foreach?

my current code is like this: 

foreach my $i (@a) {
    foreach my $j (@b) {
        if ($i eq $j) {
            undef $i; undef $j;
            last;
        }
    }
}

I can't use delete and undef just removes the contents leaving my array with lots of empty 'spaces'. How can I remove the array's cell totally and not just the contents?

Thanks.

Desmond
