Hi Monks - I have two arrays 
 

@numbers = ('25', '12', '32','56','45','21','65');
@needed = ('25','32','45','65');

I want to be able to iterate through @numbers, comparing each value to @needed. When there is a match, I want to get the match and all the values until the next match. 
e.g.    get 25 12 32   and   45 21 65

Thankyou monks, I appreciate your help. x 

 for (my $i=0; $i<@numbers; $i++)      {

   # psudocode # 

   # if $numbers[$i] matches a value in @needed;  
   # push @found, all the numbers until the next match

           for (my $k = 0; $k < @needed; $k++)   {


                 if ($numbers[$i] ==  $needed[$k])   {

                       push @found, $numbers[$i];  

    # not sure how to carry on until the next match! 
                 }

          }

   }
