You only want to use delete on an array in special circumstances. What you want is splice.

    my @array = ("index0","index1","index2","index3","index4");
    splice @array => 2, 1;  # Replace a 1 element subarray starting
                            # at index 2 with an empty list.
    # Array is now ("index0", "index1","index3","index4");
