See era post above. How you do it depends on your ultimate goal. The way era showed will store a reference to the array in $KS[1] which means any changes you make to $KS[1] will alter the array the reference points to. If you want to store a copy of the array on $KS[1] you would do this:

Code:
$KS[1] = [@kr];

That stores a copy of the array as it was at that point in the script. Any changes you make to it will not affect the original array. You will still have to use dereferencing to get to the data stored in $KS[1], but how also depends on what you will be doing later with that data. To loop through it:

Code:
for (@{$KS[1]} ) {
   print "$_\n";
}

Or to access individual indicies:

Code:
print $KS[1][0];
