The FEOV macro directs the operating system to start the end-of-volume processing before the physical end of the current volume is reached. If another volume has been specified for the data set or a data set is concatenated after the current data set, volume switching takes place automatically. The REWIND and LEAVE volume positioning options are available.

If an FEOV macro is issued for a spanned multivolume data set that is being read using QSAM, errors can occur when the next GET macro is issued. Make sure that each volume begins with the first (or only) segment of a logical record. Input routines cannot begin reading in the middle of a logical record.

The FEOV macro can only be used when you are using BSAM or QSAM. FEOV is ignored if issued for a SYSOUT data set or if the data set is closed. If you issue FEOV for a spooled input data set, control passes to your end-of-data (EODAD) routine or your program is positioned to read the next data set in the concatenation.
