That's correct. BTW, x'0F' is 15; 16 is x'10'.

In V(B) records the RDW (Record Descriptor Word) is a part of the
record, so its length is a part of the record length. You can actually
put any value in there from 5 (one data byte) through 32756 (32752 data
bytes), but for the example you cite, putting x'0B' in the correct
location within the RDW will give you an 11-byte record containing only
7 bytes of "real data".
