Thank you so much jeffa!


I do make my sub hash, it gave me all the result, but it still tell me :
Use of uninitialized value at ./lx line 97.
Use of uninitialized value at ./lx line 97.
total 10 times Use of above context.
my sub like:


sub create_hash {
my $myhashname=shift;
my %myhashname=%_;
my @keys=@_;


   unless(open(FH, ">$myhashname") ) {
       print STDERR "Cannot open file\"$myhashname\"\n\n";
        exit;}


   @myhashname{@keys}=@mydnahash{@keys};
    while (($k, $v)=each %myhashname){
    print FH "$k=>$v, "};


    close FH;
    return %myhashname;
}


and I call sub like: 

my %myeditedhash=
create_hash('myeditedhash',@editedsites, @mydnahash{@editedsites});
