I build a hash and then, I create an array of this hash and want to modify the value of one key of the hash. Although I assign the array to the built hash, it just gets the first key and value:

perl test.pl curr CD 0 AB 1 currhash CD 0 AB 0

and if I pass the reference of the hash, the hash gets modified which is not desired perl test.pl curr AB 1 currhash CD 0 AB 0

What's wrong? see the attached program Thanks carol 

#!/usr/bin/perl

sub parseFiles{
   @currArr=();

    push @currArr,'+1';
    push @currArr,'u';
    push @currArr,%currHash; # push @currArr,%currHash; in the first c
+ase

    $curr{"my"}=[@currArr];

    $curr{"my"}->[2]{"AB"}++;

    #print scalar(keys %{$curr{"my"}->[2]}), "\n";

    #print  $curr{"my"}->[0], " ", $curr{"my"}->[1], "\n";

print "curr\n";

    foreach (keys %{$curr{"my"}->[2]}){
            print  $_, " ", $curr{"my"}->[2]{$_}, " ";
    }
    print "\n";

print "currhash\n";

    foreach (keys %currHash){
            print $_, " ", $currHash{$_}, " ";
    }
    print "\n";
}
 
sub storeHash{
        $currHash{"AB"}=$currHash{"CD"}= 0;
}

sub main{
    storeHash();
    parseFiles();
}

main();
