I am writing an exit program to a RCVJRNE command.  I need to compare
before & after images on an update to a record to determine if I need to
take a specific action.  The files being journaled are getting both the
before & after images journaled.

Are an update record's UB & UP entries guaranteed (no quibble, rock-solid,
cross-my-heart) to be in 1-2 sequence, with NO possibility of another
entry being written between them?  I could not find any reference to this
in the manuals, and so I must now presume the possibility exists and must
store the UB entries in an array, waiting for the UP entry to arrive and
match to the UB entry by JOCTRR (the RRN)?  Since the program is RETURNed
without setting LR on after each entry is processed, the UB entries will
still remain in the array on subsequent calls to the program, correct?

Also, as I now see that the exit program is RETURNed without LR on after
*each* journal entry, doesn't that have the potential to be a resource
drain?

TIA, GA
