Hi MynameisAchint

I tried the same method its works fine

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

my @arr1 = (1,23,'',45," ",4);

my @arr2 = ("vinoth", " kumar", "  ", 'vin' );

@arr1 = (@arr1,@arr2);

print Dumper \@arr1

Output:

$VAR1 = 
          1,
          23,
          '',
          45,
          ' ',
          4,
          'vinoth',
          ' kumar',
          '  ',
          'vin'
        ;

All is well
