Iteration

v in A

k -> v in A

Iteration over the values in an associative array is supported as usual; in the forms above, \(v\) will take the value of successive elements in the associative array. If the dual iteration form is used then additionally \(k\) will take on the value of the associated key.

Example: Assoc Iteration (ex-adf920)

We revisit the first part of the above example and print the elements out using the dual iteration.

> A := AssociativeArray();
> A[1/2] := 7;
> A[3/8] := "abc";
> A[3] := 3/8;
> for k -> v in A do k, v; end for;
1/2 7
3/8 abc
3 3/8
