Basically, you can extract one or more elements of a particular array using an array slice.
Let's say you have an array like this:
@array = qw(a b c d e f g h i j);
And you want to use array elements 1, 3, 5 and 7. Here's how you could extract just those elements without using $array[1], $array[3], etc:
@array2 = @array[1,3,5,7]; # @array2 contains b d f h
You can also use the range (..) operator to define a start and end point for the slice.
@array2 = @array[0..3]; # @array2 contains a b c d
You can also mix and match...
@array2 = @array[0, 4..6]; # @array2 contains a e f g
Hope this helps!
