No message given. FWIW, job attributes: LOG(4 00 *SECLVL) LOGCLPGM(*YES)

Yes.

No.  In its simplest form for testing this problem, the batch job does the
override, then the RCVF loop (see code below).

You're right about my not having a full understanding of this.  So I rely
on Simon Coulter, who wrote back March 2000
(http://archive.midrange.com/midrange-l/200003/msg01449.html):

   Specify the BlockingFactor on the OVRDBF command according 
   to the effect you want to achieve:

   OVRDBF NBRRCDS(BlockingFactor) controls the number of records 
   brought from DASD to main store.

   OVRDBF SEQONLY(*YES BlockingFactor) controls the number of 
   records moved from main store to program storage (i.e., program 
   record buffer).

   NBRRCDS can be used for both sequential and keyed I/O.  SEQONLY 
   can only be used for sequential I/O.

   Sequential I/O + NBRRCDS + SEQONLY = BlindingSpeed

I don't believe I've misused the context with which this was posted, but
correct me if I have.

Ask, and thou shalt receive...

Pgm
      DclF       $DspObjdPg
      OvrDbf     $DspObjdPg  ToFile( GBALibSysF/$DspObjdPg ) +
                   NbrRcds( 100 ) SeqOnly( *Yes 100 ) +
                   Secure( *Yes ) OvrScope( *Job )
Loop: RcvF 
        MonMsg     CPF0864  Exec( Return )
      Goto Loop
Endpgm         

TIA, GA
