To appear at the 2nd International Conference on Principles and Practice of Declarative Programming (PPDP 2000), Montreal, Canada, September 20-22, 2000


Bornat has recently described an approach to reasoning about pointers, building on work of Morris. Here we describe a semantics that validates the approach, and use it to help devise axioms for operations that allocate and dispose of memory.
