arraylast( in theory

[Gary Yonaites]

I think array( and extract( works the same way as arraylast if used  
comparably. Your use is forcing a nonexistent element to the test  
array to force the "" return value. If however you let the array 
( function determine the length of the test array using the arraysize 
( function [this is what arraylast( uses in the formula] you will get  
the samr value as the arraylast returns. Why can't the only element  
in an array be both the first element and the last element? If you  
had a line of people waiting at the ticket counter and it was down to  
the final person he would be the last in line but he would also be  
the first in line. I personally think that returning "" when using  
arraylast( on a single element array would be illogical but I've got  
a nasty cold and my head is stuffed with ostrich feathers.
