F Tape Label Formats

This appendix lists the standards for the two tape label formats (ANSI version-3 and IBM-MVS) that
HP supports. In these tables, all fields of the standards are documented. However, HP does not
support all fields within these standards. For example, IBM-specific fields such as VTOC Pointer
are not supported.
NOTE: "Spaces" and "Space" in the Content column of these tables indicate fields that HP does
not support.
