Relational Navigation: Backward Pointers

Records reached via backward pointers appear to the user much like subrecords within a multiple. To display the records in the pointing file, you can define a repeating block that has a DD Number equal to the file number of the pointing file and an Index property equal to the name of the whole file cross-reference of the pointer field. See the "Displaying Multiples in Repeating Blocks" section for more information on how to define repeating blocks.
