I had an issue in my code,that's why i had asked this question and given a small example which was very close to the issue i was facing.And your reply helped me to solve the issue. i feel instead of @hash{ @array } = @array; $hash{@array} = @array ; would be better

Have you tried it like that? `#!/usr/bin/perl use strict; use warnings; use Data::Dumper 'Dumper'; my @colors = qw( white yellow green ); my %hash; $hash{ @colors } = @colors; print Dumper \%hash; __END__` [download] I get this in perl 5.8.6: `$VAR1 = { '3' => 3 };` [download] Perl assumes you want to evaluate the array in scalar context. Better to stick to the same notation everyone else uses for hash slices. HTH, Charles	[reply] [d/l] [select]

Have you tried it like that?

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper 'Dumper';

my @colors = qw( white yellow green );
my %hash;
$hash{ @colors } = @colors;

print Dumper \%hash;

__END__

I get this in perl 5.8.6:

$VAR1 = {
          '3' => 3
        };
