Most of this code is simply fetching messages from the current call 
stack queue and resending them to the caller's queue. You can 
accomplish much the same effect by using the QMHMOVPM API.

Old code but you should get the idea:

CSR   *PSSR         BEGSR
 *    ----------

 * Ensure the PSSR is not invoked if we are already handling an error
C                   IF        ( *INLR )
C                   RETURN
C                   ENDIF

C                   SETON                                        LR
                                                                     
 * Force exceptions from the API -- just in case
C                   EVAL      Qus_Ec_Bytes_Avail = *ZERO

 * Forward any messages that may indicate the problem
C                   EVAL      PSSR_msgTypes(1) = $MH_MSGT_DIAG
C                   EVAL      PSSR_msgTypes(2) = $MH_MSGT_ESCAPE
C                   CALLP     QmhMovPgmMsg( *BLANKS               :
C                                           PSSR_msgTypes         :
C                                           %ELEM(PSSR_msgTypes)  :
C                                           $MH_RPG_IV_ENTRY + PSDS_Pgm 
:
C                                           $MH_REL_MSG_Q_PRV     :
C                                           Qus_Ec :
C                                           20     :
C                                           '*NONE     *NONE     ')
                                                                        
 
 * Indicate a catastrophic failure
C                   CALLP     sndSmbEscpMsg( $SMB_FAILURE :
C                                            ''           :
C                                            $MH_RPG_IV_ENTRY + 
PSDS_Pgm )

C                   RETURN
CSR                 ENDSR
