FEOV (Force End of Volume) Macro
The macro is used for files on magnetic tape (programmer logical units only) to force an end-of-volume condition before sensing a reflector mark.
This indicates that processing of records on one volume is considered finished, but that more records for the same logical file are to be read from, or written on, a following volume. For system units, see the SEOV (System End-of-Volume) Macro.
When physical IOCS macros are used and DTFPH is specified for standard label processing, FEOV can be issued for output files only. In this case, FEOV writes a tapemark, the standard trailer label, and any user-standard trailer labels if DTFPH LABADDR is specified. When the new volume is mounted and ready for writing, IOCS writes the standard header label and user-standard labels, if any.
