The  Compare Member  Description command  compares  attributes of  one,
generic,  or  all members  (either  data or  source)  in two  different
files.   Only the  member text, source type,  number of records, number
of deleted  records, and  'share'  attribute are  compared.   Unmatched
member names  in the To  file are flagged.   Unmatched member  names in
the  From file may be optionally flagged.   CMPMBRD may be helpful when
ensuring member attributes are identical in two files.

If a specific  or generic member  name is specified,  only the  members
matching the name are checked.

A typical command would be:

             CMPMBRD  FROMFILE(xxx) TOFILE(yyy) MBR(*ALL)

A listing would  be output with one  line per member in  the From file.
If  differences exist, additional lines  would be listed  with both the
From value and To  value for each  member.  Any  members that exist  in
the From  file  and not  the To  file would  be flagged.   Because  the
default is  to check for the  inverse condition, any members  in the To
file that do not exist in the From file would be flagged.

Only the following values are compared:

      - Member text
      - Source type (if any)
      - Number of active records
      - Number of deleted records
      - SHARE attribute

Escape messages from based on functions will be re-sent.

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

   FROMFILE      The  qualified  name of  the From  file.   The library
                 value  defaults  to *LIBL.    A  specific  library  or
                 *CURLIB may also be used.

   TOFILE        The qualified  name of  the To file.   The  default is
                 *FROMFILE  meaning the same  name as the  From file in
                 which case a  different library  must be  named.   The
                 library value defaults  to *LIBL.  A  specific library
                 or *CURLIB may also be used.

   MBR           The  member  name  or  generic  name  to be  compared.
                 *ALL is  the  default  meaning all  members  would  be
                 compared.

   SAMEMBRS      A *YES/*NO  parameter for whether  to ensure  the same
                 members exist in both files.

                 *YES is the default to ensure the same members.

                 *NO may be specified to prevent checking.

   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.
