The Check  Based on File  command ensures that  all logical files  in a
library are based on physical files in the same library.

A typical command would be:

             CHKBOF    LIB(xxx)

CHKBOF is the companion tool for CHKDBD.

  **   CHKDBD checks  the physical files  in a library.   It determines
       if  there  are  any  dependent  logical  files  outside  of  the
       library.

  **   CHKBOF checks  the logical files  in a  library.  It  determines
       if they are based on physical files outside the library.

To  ensure  that a  library  'stands  alone',  both CHKDBD  and  CHKBOF
should be run.

To  ensure that  all  libraries on  the system  'stand alone',  use the
CHKALLDBD tool.

Handling of Join Logical Files
------------------------------

Normal logical files  are processed  using the file  QAFDACCP which  is
output by DSPFD TYPE(*ACCPTH).

Join  logical files  are processed  using  the file  QAFDJOIN which  is
output by DSPFD TYPE(*JOIN).

Command parameters                                    *CMD
