Dave those are ANSI tape labels.  Unix does not use them    DEC did
although was inconsistent with the use particularly WRT HDR2 records.  Tom
Quarles (of spice 3 fame) wrote probably the best version for Unix to deal
with them.  I believe I gave a copy but it will be in BSD 4.1 maybe 4.2
compiler syntax. I'll ask him if he ever updated it. Clem
