 ;;^DD(.4014,9,21,1,0)
 ;;= Piece 1 is always null
 ;;^DD(.4014,9,21,2,0)
 ;;= Piece 2 is the static part of the cross-reference: ex. DIZ(662001,"B",
 ;;^DD(.4014,9,21,3,0)
 ;;= Piece 3 is the global reference: ex. DIZ(662001,
 ;;^DD(.4014,9,21,4,0)
 ;;= Piece 4 tells FileMan how many variable subscripts must be sorted
 ;;^DD(.4014,9,21,5,0)
 ;;=through to get to the record number, plus 1 for the record number
 ;;^DD(.4014,9,21,6,0)
 ;;=itself.  ex. for a regular cross-reference, ^DIZ(662001,"B",X,DA),
 ;;^DD(.4014,9,21,7,0)
 ;;=the number is 2.  One for the value of the X subscript, and one for the

 ;;=The IX nodes are normally derived by FileMan during the entry of sort
 ;;^DD(.4014,9,23,2,0)
 ;;=fields (in routine XR^DIP).  However, they can also be passed to the
 ;;^DD(.4014,9,23,3,0)
 ;;=print (^DIP) in the BY(0) variable to cause FileMan to either use a MUMPS
 ;;^DD(.4014,9,23,4,0)
 ;;=type cross-reference, or a previously sorted list of record numbers.
 ;;^DD(.4014,9,23,5,0)
 ;;=Fileman sometimes builds the IX node prior to calling the print, as in
 ;;^DD(.4014,9,23,6,0)
 ;;=the INQUIRE option, where the user then goes on to print the records.

 ;;=either a numeric, date, set-of-codes or free-text field, and does not have
 ;;^DD(.4014,9.5,21,5,0)
 ;;=an output transform.  If this node exists, it will be set to the static
