  The dump is presumably for CPA0701 [or the CLLE equivalent] due to an 
unmonitored exception message.  The CPF2204 is a diagnostic message, and 
that will not be the origin for the /dumping/ for the error; i.e. the 
diagnostic is merely /logged/ to the program message queue.

  Apparently then the Grant Object Authority request will not be built 
dynamically for the system on which the request will be run, but 
hard-coded and compiled static into a CLP or CLLE.  In that case just 
monitor for the exception, and in response to that error, as the coded 
handler, verify that the only diagnostic messages are the CPF2204 for 
user profile names that are acceptable to be ignored.

  Even if not coded fully dynamic, a list of only existing user 
profiles as obtained from a list [effective array] could be specified as 
elements on the USER parameter; replacing any missing *USRPRF object 
with a mandatory user profile name.  So for example if the list of users 
to assign authority is (APPLUSER OPTIONAL) [coded as USER(&U1 &U2)] 
where user APPLUSER is mandatory and user OPTIONAL is optional and does 
not exist, then the request coded as GRTOBJAUT USER(&U1 &U2) could be 
modified so &U2 is changed from 'OPTIONAL' to 'APPLUSER' so the request 
resolves to the redundant yet acceptable request: GRTOBJAUT 
USER(APPLUSER APPLUSER).  Another option is to ignore the CPF2204 for 
optional users... described in code later below.

  As described earlier, the CPF2204 is not the exception, so the MONMSG 
CPF2204 is not doing anything.  More specifically, the exception is 
CPF2227 but because that is not being monitored, the CL default 
exception handler is presumably being called to send an inquiry message 
which is replied to with 'D'=Dump in response.

  Correct.  The CPF2204 can not be monitored because that message is 
not one of the messages issued as an exception message; thus why the 
message is not listed in the help text for the command.

  The following algorithm should suffice for ignoring some cases of 
CPF2204 for a chosen user profile name, though easily expanded to ignore 
multiple user profiles; noting effectively the same is done for one [or 
more if expanded] mandatory user profiles that must not be ignored:

[code]

dcl &mi *char 07
dcl &md *char 100/* cpf2204 &1 *char 10 UsrPrf name       */
/* the length 100 covers most other possible diags        */
dcl &up *char 10
dcl &xk *char 04 /* cpf2227 exception msg key; for resend */
 ?grtobjaut (mylib/uln*) *file aut(*all) ??user(bogus appUser myUsr)

         keyvar(&mk) msgdta(&md) msgid(&mi)

  if cond(&mi *eq 'CPF2204') then(do)
    chgvar &up %sst(&md  1 10)
    /* if &up in list_of_mandatory then bad_thing: */
    if (&up *eq 'APPUSER   ') then(do)
      /* mandatory user can not be ignored; send diag as escape */
      sndpgmmsg *n cpf2204 qcpfmsg tomsgq(*topgmq) topgmq(*prv (*)) +
                msgdta(&md) msgtype(*escape)
    enddo /* escape message terminates this pgm */
    /* if &up in list_of_optional then(do) */
    if (&up *eq 'BOGUS     ') then(do)
      /* remove any cases that are ignored */
      rmvmsg pgmq(*same (*)) msgq(*pgmq) msgkey(&mk) clear(*bykey)
    enddo
    goto Next2204
  enddo
  else do /* only cpf2204 is processed by this pgm */
    /* leave whatever is the unprocessed diag(s)   */
    /* resignal CPF2227 exception using the saved key */
    call qmhrsnem (&xk x'0000000000000000')
  enddo
  NoMoreDiag:
