I'm back onto this problem.
I wrote a proof-of-concept program and it works.
I've modified an existing z/OS product and my changes don't work.
Only DSNAME and DISP are coded on the DD statements.
1st file is VB with LRECL=200
2nd file is VB with LRECL=230
3rd file is FB with LRECL=1000.

I don't see a question, so I'm responding to what I think you want.
It has long been true that BUFSIZE defaults to the largest
available BLKSIZE The requirement was written in the 1980s. (It might
depend on your access method.) So, I very much doubt the the BLISIZE
difference is the problem.
I have provided the DCB in source and dumped it just before the OPEN.
1st data set in the concatenation :
Data Set Name . . . . : PIERRE.VB200.

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:
Note that RECFM=V is missing the "B" (i.e. block descriptor
word). RECFM=V is almost the equivalent of RECFM=U, exceptt that the
data block is prefixed by a half-word length (limited to 32767) and "BB".
BTW, a VBS record can be as long as 16,777,215 bytes,

OK, but what is in the source coded on the DCB? Does it specify BLKSIZE
and/or LRECL.
Please provide the DCB from the source of the program.

It's possible to override attributes of an existing data set in JCL DD,
DYNALLOC, or DCB.
If the OPEN is only for READ overriding attributes will be
These are existing datasets so it's just DSNAME and DISP in the concatenation.

Would not think "V" could be included. "VBS" is just a variation of
"VB" where the RDW is treated as a SDW where X'' in the "BB"
field indicates a non-segmented (i.e full variable length record" in
the buffer).
Another approach would be to not open the file as concatenated, but
treat

In fact, can't any mixture of RECFM=V, VB, and VBS be overriden
Presuming the program is assembler, I would suggest trying
hard-coding for RECFM=VBS, LRECL=32767, BLKSIZE=32760, BFTEK=A.
And presuming all the files are RECFM=VBS.
If you do your own segmented record, LRECL=X ought to work.

Isn't there a BUFL parameter that accomplishes the same thing and can be used
without regard to actual BLKSIZE (in the case of RECFM=FB)?
