Line 192:

* Operators exist to convert words into lists, and lists into arrays and back again.

* This data type has the advantage over array in that it is infinitely expandable Data is extracted using the the operations first, butfirst, last, butlast, member and item. Data is added using sentence fput and lput.

* A list can be considered to be a queue with the operators queue and dequeue, or a stack with the operations push and pop.
