>I have realized the task and do it 'almost recursively', cause I have aded the combined elements at the end of the list and do not end the combinations while do not hit the last element. Work very well. Thanks!

Yep, many recursive algorithms can be easily converted to "for" or "do while" cycles (like in this case - it can be a For cycle from 1 to reccount... But I wanted that you got it!)
