Output card type of a functional map
The type of the output card in a functional map is the type whose map rule includes the functional map name. For example, if the functional map name is entered in the rule cell for CarRecord(s), the output of that functional map must be CarRecord.
The output of a functional map must match the output data object (where the map rule that calls the functional map is), therefore a functional map has only one output card.
A functional map may have only one output card.
