These functions allow you to recognize values that are cross references and to read the records they refer to.
|bool reference(string)||Reference returns true if its string argument is a cross reference value, that is, the internal key of one of the records in the database.|
|node dereference(string)||Dereference returns the node tree of the record referred to by the cross reference string argument.|
|node getrecord(string)||Getrecord is the same function as dereference.|
