$#a = 4; # gives it the length 5

You have to shorten the array as fast as you make it longer than 5:
@a = (1,2,3,4,5,6,7);
$#a = 4; # @a = (1,2,3,4,5)

@a = (1, 2, 3, 4, 5, 6, 7); # Now are there 7 elements again.

I Think I Need To ReDo That One.
I Need To Make An Array Using Only The Last 5 Elements Of @a.

@b=@a[-5..-1];
@b=splice(@a,-5); #if you want to remove those elements from @a
