Display Duplicate  Command is  intended to  check if duplicate  command
names  exist in two  libraries or in  one library  and the rest  of the
system.    Having  duplicate  command  names  can  be  an  integrity or
security exposure.   The  typical uses  would  be to  ensure your  user
command names are not found in either QSYS or TAATOOL.

*ALLOBJ  authority is  required if  the FROMLIB  value requests  to run
over all user libraries.

A typical command would be:

             DSPDUPCMD   FROMLIB(*ALLUSR) TOLIB(QSYS)

This  would find  all  commands in  user libraries  (including TAATOOL)
and check if the same name also exists in QSYS.

Another typical command would be:

            DSPDUPCMD    FROMLIB(*NONTAA) TOLIB(TAATOOL)

This would  find all  commands in  user  libraries (excluding  TAATOOL)
and check if  the same name also exists  in TAATOOL.  If  a TAA command
library exists  other than TAATOOL, it is  also excluded by the *NONTAA
request.

DSPDUPCMD escape messages you can monitor for
----------------------------------------------

None.  Escape messages from based on functions will be re-sent.

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

   FROMLIB       The library  to get  the list  of commands  from  that
                 should be checked  to see if  the same name  exists in
                 the TOLIB.

                 The  special value  *ALLUSR  may be  entered  to check
                 against   all  user  libraries.    This  includes  the
                 TAATOOL library.

                 The special value *NONTAA  may be entered to  find all
                 commands in  all user libraries  excluding the TAATOOL
                 library.     If  a   TAA  command   library  has  been
                 specified,  it  is  also   excluded.    You  may   use
                 DSPTAALIC  to determine  if a  command library  exists
                 other  than TAATOOL.   If  so, it  means that  the TAA
                 commands exist  in  both  the TAATOOL  library  and  a
                 separate library for TAA commands.

                 If  FROMLIB  is  *ALLUSR or  *NONTAA,  you  must  have
                 *ALLOBJ special authority.

   TOLIB         The  To  library  where  the  commands from  the  From
                 library  will  be  checked against.    The  default is
                 QSYS.

   CMD           The Command to  be checked.   *ALL is the default  for
                 all commands  in the From  library.  A  single command
                 or a generic command name may also be entered.

   OUTPUT        How  to  output the  results.    * is  the  default to
                 display the  spooled file  if the  command is  entered
                 interactively.  The  spooled file is deleted  after it
                 is displayed.

                 If  the  command  is entered  in  batch  or *PRINT  is
                 specified, the spooled  file is  output and  retained.

Restrictions
------------

You must have *ALLOBJ  special authority to specify a  FROMLIB value of
*ALLUSR or *NONTAA.
