cool. the square brackets was the correct method to do a ref to array...missed it although I read about it last night.thanks.

several questions

PROBLEM: the array seem to list of all of the numbers found in both files. I want to only print out the numbers that are fund on BOTH in one file then the numeri not found in the other into another file

my IF check doesn't seem to work?

push @{$hash{$key}},$value if $hash{$key}; #non so come funziona "push" 

how is this piece of code work? I don't understand the "[1]", I think 
+it's a matrix , is it placement spot??

[download]
$hash{$italian}[1] = $french;
