sort(X, i) produces a list containing values from X.

If X is a record, list or set, sort(X, i) produces the values of X in sorted order.

If X is a table, sort(X, i) produces a list obtained by sorting the elements of X, depending on the value of i. For i = 1 or 2, the list elements are two-element lists of key/value pairs. For i = 3 or 4, the list elements are alternative keys and values. Sorting is by keys for i odd, by values for i even.
