Error description

• While trying to autoconnect to another region, an IRC session
  is successfully started. An attempt is made to send data
  using an IRC SWITCH SEBSEQUENT call. One side has DISCONNECTed
  while a SWITCH SUBSEQUENT was being process by DFHIRP on that
  session. DFHIRP is at V3.2 level. DFHIRP issues RC x'000000F8',
  IRERRIDL. The region experiences DFHIR3784 error code x'DD3C'.

  ****************************************************************
  Two CICS systems were connected using an MRO cross memory
  (XM) connection. On one of the systems the connection was
  quiesced using an IRC QUIECSE IMMEDIATE command. The other
  system attempted to reconnect and as part of this processing
  it issued an IRC SWITCH SUBSEQUENT command. However,
  processing of the DISCONNECT from the other system was
  delayed because the system was busy. It was eventually
  processed at the same time as the SWITCH SUBSEQUENT and
  this resulted in an error. The error code should have
  been IRERRCFT (x'24' - set footprint failed), but when
  looking up the error code in a table, DFHIRPSW failed to
  set up an index register and so incorrectly set the return
  code to be the first entry in the table - IRERRIDL (x'F8'
   - Total data length invalid for SWITCH or PULL). This
  return code is unexpected on a SWITCH SUBSEQUENT and so is
  treated by DFHIRP as a serious error, resulting in the
  reported message DFHIR3784. The correct return code, IRERRCFT,
  is expected and does not result in any error message.
  Many errors issued out of IRC SWITCH or PULL processing will
  issue an incorrect return code of IRERRIDL which may
  be unexpected and so unpredictable results may occur.
  

Problem conclusion

• DFHIRPSW has been altered to correctly index into the LASTRCOD
  table of return codes.
