perhaps I didn't fully understand your comment but i changed my program based on use strict. I still have problem

If I don't use the hash ref, I get this error Can't use string ("CD") as a HASH ref while "strict refs" in use at ./test.pl line 15.

and if i use hash ref, I don't get any value for the key CD Don't know why?! curr CD AB 1 currhash CD AB 1

The desired output is curr CD 0 AB 1 currhash CD 0 AB 0 

#!/usr/bin/perl
 use strict;

sub parseFiles{
   my @currArr=();
my %curr;
my %tmp = $_[0];

    push @currArr,'+1';
    push @currArr,'u';
    push @currArr,%tmp; # push @currArr,%currHash; in the first case

    $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 %tmp){
            print $_, " ", $tmp{$_}, " ";
    }
    print "\n";
}
 
sub storeHash{
my %currHash;

        $currHash{"AB"}=$currHash{"CD"}= 0;
    return %currHash;
}

sub main{
my %currHash;
    %currHash=storeHash();
    parseFiles(%currHash);
}

main();
