End-of-Volume and End-of-File Label Processing for OS
An end-of-volume or end-of-file condition occurs when:
- A tape mark is read.
- The physical end of a tape is reached.
- The FEOV (forced end of volume) macro is issued.
Following is a description of the end-of-volume (EOV1 and EOV2) and end-of-file (EOF1 and EOF2) label processing.
