I have a small problem perl code program maybe you can reply within a few minutes.. My problem is that I transfered my data into hash(hash of hash)... I can access any element in hash in our loop.. But When I try to access from  out of loop or out of function I cant... I initilizaed empty hash but I didnt work.. How can use my hash,and how can I make it global... If you have time and if you can look my code , I will be happy... Thanks..here my code

#!/usr/bin/perl

$putword=0;
$q63=7;

&getfile("query63.txt");

sub getfile   {
open (FILE, $_[0]);


my @data = <FILE>;
close (DATA);


for($i=0; $i<=$#data;$i++){

$index=$i;



@words=split(/\s+/,$data[$index]);
$count=$#words;

                                           

if($count==2)  {   

@words = split(/\s+/,$data[$index]);
$count=0;
$putword=$putword+1;



if ($words[2] != 0){

 $ctf=$words[1];

$df=$words[2];


}


}

else {

@words = split(/\s+/,$data[$index]);




 %query=($putword =>{ctf=>$ctf,
                    df=>$df,
                    $words[1]=>{doclen =>$words[2],
                                tf =>$words[3],
                         }
                    },
       );
       
       
#When I write here,I can get value..here inside the loop   
#print $query{2}{1}{doclen};





}




}

#when I write here,I got nothing,,this is outside of loop..
print $query{2}{1}{doclen};But 


}
