The  Display Message  Use  command displays  the  commands that  use  a
common monitorable message.

A typical command would be:

         DSPMSGUSE     MSGID(CPF2105)

A  subfile would  be displayed of  the commands  that send  the CPF2105
message as a monitorable message.

The   companion  tool  is  DSPMONMSG  which  displays  the  monitorable
messages for a command.   The files used  by DSPMSGUSE are part of  the
DSPMONMSG tool.

Which commands are supported
----------------------------

The information  for the messages is extracted  from system information
on  the  system.    This  information  contains  both  system and  some
licensed product commands.

The TAA Productivity Tool commands are  not included.  Most of the  TAA
Productivity Tool commands follow the convention of:

  **   CPF9898  is  sent if  an  interface  error  occurred such  as  a
       parameter can  only be *YES or  *NO and *XX is  passed or if the
       message is not  considered to  be one  a program  would want  to
       monitor for.   The  message data  (the text of  the message)  is
       coded in the program.

  **   A  specific message is  sent in  the range  TAA9881-TAA9898 from
       the  TAAMSGF  in  TAATOOL if  the  message is  considered  to be
       monitorable.  The message  IDs are unique within a  program, but
       the  same message  ID may  be  re-used in  a different  program.
       The  message data is coded in the  program.  The message IDs are
       described in the tool documentation  and are often described  in
       the command help text.

A few  tools such as  PMTOPR or DYNMNU  send specific messages.   These
are described in the tool documentation.

Command parameters                                    *CMD
------------------

   MSGID         The  message   ID  which  is  sent  as  a  monitorable
                 message by commands.
