The  Compare  Logical  File  Description  command  compares  the  CRTLF
command  parameters of  two Logical file  objects.   A spooled  file is
created of any differences.

The major attributes which are not compared are:

      - Owner
      - Authorizations
      - Text description
      - Create date and time
      - Source file and member name
      - Source data

A typical command would be:

             CMPLFD    FROMFILE(xxx) TOFILE(yyy)

A spooled file would be created with any differences shown.

Some  comparison  of non  CRTLF values  occurs such  as the  'number of
formats', whether a  Join file exists, and  the number of members  that
exist.

An option  exists to send an  escape message if differences  exist.  An
option exists to delete the spooled file if no differences exist.

Most  of  the  attributes (but  not  all) are  compared.    CMPLFD uses
RTVLFA and is limited to the attributes returned on RTVLFA

CMPLFD  escape messages you can monitor for
-------------------------------------------

      TAA9895    Differences exist (optional based on ESCAPE parm)

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

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

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

   TOFILE        The  qualified name  of the  To  file to  be compared.
                 The default is  *FROMFILE meaning the  same file  name
                 as  in the  FROMFILE  parameter.   The  library  value
                 defaults to  blanks.  If no name  is entered, *LIBL is
                 assumed.  *CURLIB may also be used.

   ESCAPE        Whether  to  send  an  escape  message  if differences
                 exist.  The  default is *NO  which means a  completion
                 message is sent.

                 *YES may  be specified to send  TAA9895 if differences
                 exist.

   DLTSPLF       Whether  to delete  the spooled  file if there  are no
                 differences.    The  default   is  *YES  meaning   the
                 spooled file is  deleted if no differences  are found.
                 The  spooled file  is  always retained  if differences
                 exist.

                 *NO may be  specified to  ensure a  spooled file  will
                 exist  regardless  of  whether  differences  exist  or
                 not.

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

Most  of  the attributes  (but  not  all) are  compared.   CMPLFD  uses
RTVLFA and is limited to the attributes returned on RTVLFA.

Prerequisites
-------------

The following TAA Tools must be on your system:

     CHKOBJ3         Check object 3
     EDTVAR          Edit variable
     RTVLFA          Retrieve logical file attributes
     RTVSYSVAL3      Retrieve system value 3
     SNDCOMPMSG      Send completion message
     SNDESCMSG       Send escape message

Implementation
--------------

None, the tool is ready to use.
