Spanned Records-VSAM

Spanned records
Spanned records are logical records that are larger than the CI size. To have spanned records, the file must be defined with the SPANNED attribute at the time it is created. The RDFs describe whether the record is spanned or not.

A spanned record must always begin on a control interval boundary and fills one or more control intervals within a single control area. A spanned record cannot share the CI with any other records. In other words, the free space at the end of the last segment is not filled with the next record. This free space can only be used to extend the spanned record.
