=={{header|Standard ML}}==
Like OCaml, Standard ML doesn't have pointers but have a "ref" mutable data structure which is the basis of mutability in Standard ML:
<lang sml>
val p = ref 1; (* create a new "reference" data structure with initial value 1 *)
val k = !p; (* "dereference" the reference, returning the value inside *)
p := k + 1; (* set the value inside to a new value *)
</lang>
