    i have problem with hash printing !!!

    You could guess that any such problems could be easily resolved... did you try something like this:

    print "$k => $h{$k}\n" for my $k (sort keys %h);
    ?

    -sauoq
    "My two cents aren't worth a dime.";

      Hmm...

      my %h = ( a => 1, b => 2, c => 3 ); print "$k => $h{$k}\n" for my $k (sort keys %h);

      Output:

      syntax error at D:\progs\perl\junk.pl line 5, near "$k (" Execution of D:\progs\perl\junk.pl aborted due to compilation errors.

      Maybe you meant something like:

      print "$_ => $h{$_}\n" for sort keys %h;

      Or the (no doubt) more newbie-friendly:

      for my $k ( sort keys %h ) { print "$k => $h{$k}\n"; };

        ++ seven hours and several upvotes later. It's amazing how few people are trying around here these days.
