I think I'm not wrong asking for help here, I tried very much, searched very much too before posting the question here, the real trouble is, I did not know for WHAT to search, now I know, the name of what I'm searching for is "jump table". Its hard to me write and read in english, so I'm trying to do my best before bothering you. Of course, I'm always very thankful for all help you are giving, and to be member of this marvelous forum!
