                                   successfully registered.  There is
                                   either an EXE handler with the same
                                   name registered in another process,
                                   or a DLL handler with the same name
                                   registered in another DLL.  (To
                                   address this exit handler you must
                                   specify its library name.)

                                   (RexxRegisterExitExe or
                                   RexxRegisterExitDll); the exit
                                   handler is not registered (other
                                   REXX exit handler functions).
