Uh, I'll take note, but the Towers are done elsewhere.

The close after writing some number of feet is how most Unix programs write
to tape; it works most of the time, but what happens if you have a short
reel?  It's not handled very gracefully, as a rule......  That's why a
standard, industry-compatible way of doing it would be such a blessing.

Not as far as I know.  Again, the Tower development is done in Columbia, SC,
and I can't speak for them.  If you want it done, send in a bug report via
your NCR rep.  As a "real user" you probably have more leverage than do I.
