* ``assign(id, val)`` -- assigns val to id, then returns val. id must be an identifier, not an expression
* ``booksize()`` -- returns the value of the |app| 'size' field. Returns '' if there are no formats.
* ``cmp(x, y, lt, eq, gt)`` -- compares x and y after converting both to numbers. Returns ``lt`` if x < y. Returns ``eq`` if x == y. Otherwise returns ``gt``.
* ``divide(x, y)`` -- returns x / y. Throws an exception if either x or y are not numbers.
