in thread arrays

Hmm....actually, that doesn't really help at all!

If you want to know the index of the last element of an array, do this:

@letterList = ("a", "b", "c", "d"); #refer to the last array index #using '$#array' syntax: print $#letterList;
This will, of course, output "3".

You can also refer to the value of the last element of the array
using negative indices, e.g. $letterList[-1] will also refer to "d".
