I'm not even sure if FLX under RSX can access DOS DECtapes... I think FLX only

seem obvious there should be one.
Yes, there is, different from everything else as far as I know. I think the DECtape
format is faintly related. Some DOS manuals may give some clues, but I've never
looked into it or had any exposure to DOS disk file system internals.

FLX accessing DOS tapes will "fail" at 2035.
That figures, because the RSTS date format was taken from DOS-11. I assume you meant
magtape; DECtape runs into trouble in 2002 because there the date is only 15 bits (the
sign bit is used to mark a contiguous file).
