Creating or editing IMS datasets by using XREF editor

A record layout cross reference (XREF) is used to automatically match record layouts to data records for those functions that use layouts to format data. An XREF is needed when the data being formatted requires more than a single record layout. The XREF is a cross-reference between each data file record and the corresponding layout. For more information, see XREF-Processing.
