Syntax for controlling message management

To control message management, MPFLSTxx recognizes one parameter, msgid, and four statements: (.DEFAULT, .NO_ENTRY, MPFHCF, and .MSGIDS)
The syntax of the message processing record (msgid) is:
msgid     [,AUTO  [(YES)  ]  ,RETAIN  [(YES)   ]  ,SUP [(YES)]]
          [       [(NO)   ]           [(NO)    ]       [(ALL)]]
          [       [(TOKEN)]           [(I,E,CE)]       [(NO) ]]
          [                                                   ]
          [[,USEREXIT(exitname)][/*comments*/]                ]
The syntax of the .DEFAULT statement is:
.DEFAULT  [,AUTO  [(YES)  ]  ,RETAIN  [(YES)   ]  ,SUP [(YES)]]
          [       [(NO)   ]           [(NO)    ]       [(ALL)]]
          [       [(TOKEN)]           [(I,E,CE)]       [(NO) ]]
          [                                                   ]
          [[,USEREXIT(exitname)][/*comments*/]                ]
The syntax of the MPFHCF statement is:
MPFHCF=[x/&]
The syntax for the .MSGIDS statement is:
.MSGIDS NOCHANGE
The syntax of the .NO_ENTRY statement is:
.NO_ENTRY [,AUTO  [(YES)  ] ,RETAIN [(YES)   ] ,SUP[(YES)]]
          [       [(NO)   ]         [(NO)    ]     [(ALL)]]
          [       [(TOKEN)]         [(I,E,CE)]     [(NO) ]]
          [                                               ]
          [[/*comments*/]                                 ]
