The Compare  Library Description  command compares  the CRTLIB  command
parameters of  two Library objects.   A spooled file is  created of any
differences.

The major attributes which are not compared are:

      - Owner
      - Authorizations to the library
      - Text description
      - Create date and time

A typical command would be:

             CMPLIBD   FROMLIB(xxx) TOLIB(yyy)

A spooled file would be created with any differences shown.

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

Note that the authorizations to  the library are not compared,  but the
CRTAUT and CRTOBJAUD values are compared.

CMPLIBD 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
------------------

   FROMLIB       The name of the From Library to be compared.

   TOLIB         The name of the To Library to be compared.

   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.
