  ----------------------------------------------------------------
  This seems to be an error in FRXUORM0.
  1. In FRXUORM0, RVGetBuffers at next SEQ# incorrectly specify
     WAIT=NO.
      09158820,18256102,18457651,18519410,18634610,18745940,
      29570200,29570550,29572203,29572251,29572620
     These lines need to specify WAIT=YES or need to check whether
     the buffer was ontained or not.
  2. FRXQBUF0 SEQ#10160000 is wrong. It specify WAIT=NO, but does
     not check rvgb_qb_ret_ddrf = nil.

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    GEN:
  
  *** END IMS KEYWORDS ***
  FRXUORM0 and FRXQBUF were modified to check if we obtained the
  buffer. If we didn't get a buffer, then spill the record and
  try to get buffer again. If we still didn't get buffer then we
  abend.
