FILEFDBCK       EXTERNALLY DESCRIBED FILE FEEDBACK     TAABCKX

The  File Feedback  function  provides  externally described  files  to
allow  the file  feedback  areas (also  known  as I/O  Feedback)  to be
easily accessed in an RPG program.

This  eliminates having to look  in the manual and  add offsets to find
the proper from/to locations.

There are three different externally described files supplied:

    TAABCKIP   - Used for ICF or Display files
    TAABCKPP   - Used for Printer files
    TAABCKDP   - Used for data base files

Tape and diskette  files only use  the common information available  in
most of the files.  Use the TAABCKDP file to extract this.

Assume you want  to access the relative record number  of a record read
from  a data  base  file.   You would  normally code  the RPG  specs to
define the  file  continuation line  and  the  Data Structure  line  as
follows:

     FFILEA   IF  E           K        DISK         KINFDS FDBCKD
     .
     .
     IFDBCKD    E DSTAABCKDP

Compiling the program  with these statements will allow you  to look at
the  external descriptions  of the fields  in the  compilation listing.
You need to find  the field name used  for the relative record  number.
You could also determine the name by the use of DSPFFD TAABCKDP.

The name  for  the relative  record number  field used  in TAABCKDP  is
FDRR.  You  would code this in your program  as a normal decimal field.

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

No command is provided.

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

  **   The  files  describe  the  RPG  feedback  area.    This includes
       fields which are unique to the RPG language.

  **   In some  cases, fields  overlap in the  feedback area  depending
       on the  type of  feedback provided.   The normal field  usage is
       described  in the files  provided.  If  you have a  need for one
       of the fields  not described, you must  use a program  described
       data structure.

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

None.

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

None, the tool is ready to use.
