The close routine does not process trailer labels on an input data set. Usually, the trailer labels are processed by the EOV routine before the data set is closed unless deferred user input trailer label processing was specified in the DCB exit list. If deferred user input trailer label processing was specified, the processing otherwise performed for an input end-of-data condition is performed when an input data set is closed.

If an input data set is closed before it reaches the end of data set or the end of volume, or if the FEOV macro is executed, processing of trailer labels is not performed.
