note giulienk I'm no expert in objects but i read in [id://192380] (point 5) that Java doesn't bring objects to the limit as, for example, integers aren't really objects. Again i'm no authority in the field but maybe someone else could point out exactly what's the problem in your point 7 and Java as an OO example. <P><BR><TT>$|=$_="1g2i1u1l2i4e2n0k",map{print"\7",chop;select$,,$,,$,,$_/7}m{..}g</TT> 218778 218778
