You cannot do that. An array element can hold a scalar, i.e. a string, a number, or a reference. The reference can be a "handle" to another array, so you can say

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

but that's probably not what you want; printing $KS[1] will produce something like ARRAY (0x1CC01BED) and you have to use ${$KS[1]}[0] to access the first element of @kr, etc.

Another option would be to use splice to replace $KS[1] with all the elements of @kr, meaning $KS[1] will be the first element or @kr, $KS[2] will be the second, etc. http://perldoc.perl.org/functions/splice.html
