  *                      the OM listen exit, but that listen     *

  ****************************************************************
  With this apar, the use of the SPOC's OM listen exit is
  managed differently.  In particular, the listen exit is
  not used within the TSO SPOC.  Within the REXX SPOC API,
  the listen exit is only used when an OM subscription
  is issued by the user's rexx program.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/SYS SYS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  This apar changes the way the SPOC listen exit for OM is
  used.  The listen exit is an internal component with no
  defined user interface.
  
  The SPOC listen exit for OM is no longer used in the TSO
  SPOC.
  
  In the REXX SPOC API, the listen exit is only loaded and
  used when the rexx program issues a subscription request.
