Ok - I feel real stupid asking something as dumb as this but hey I'm a complete newbie... Let's say I've got an array and I'm using a foreach loop to divide a number by all the numbers in the array and each time I get $number % $number_from_array == 0 I want to add that number to the end of the array. Somehow this leads to the array being mixed up a bit when running through the foreach loop. This is the code I'm using: 
print "Enter a limit\n";
$limit = <STDIN>;
@primes = (2);
$number = 2;
$something = 1;
while ($number < $limit) 
    {
        $something = 1;
                
                foreach $div (@primes)
            {
                print "Dividing $number by $div\n";
                    if ($number % $div == 0) 
                    {
                        print "$number ist no Primnumber\n";
                            $number++;
                        $something = 0;
                    }
            
            }

    if ($something == 1) 
        {
        print "$zahl is no prime number\n";
        push (@primes, $number);
        $number++;
        }
    }

Yeah... you gessed right - I'm trying to make a program that works out prime number up to a certain limit... I know this is really inefficient, weird, etc. but I've only started programming. Thanks for your help in advance, Martin
