I would probably use the following file equations instead:

  :file in; dev=x; rec=-16384,1,U
  :file out; dev=y; rec=-16384,1,U

Why? Blocks on the tape might be of different sizes (eg a STORE
label might use 80B whereas data blocks might be much larger).
The (U)ndefined rec size above prevents padding or truncating.

TapeCopy from Jazz might also work in this context, but similar
to FCOPY it does not really understand the data it copies (raw
copy), so it is not able to merge multiple reels to one DDS like
Allegro's XOver, for example.
