Interesting. When transferring to ASCII platforms, the BDW and RDW
are stripped off, though RDW can be retained with a SITE command.
So RECFM=V could be included as a like attribute file for concatenation.

This says otherwise:

Format-V records
Last Updated: 2023-03-29
Figure 1 shows blocked and unblocked variable-length (format-V)
records without spanning. A block in a data set containing unblocked
records is in the same format as a block in a data set containing
blocked records. The only difference is that with blocked records
each block can contain multiple records.
See particularly the part of the figure labelled "Unblocked records".
