RPG/400 Definition (was Using VARLEN DDS keyword)

I agree!  I buy lots of RPG books, and just take for granted that any newly
published books are going to be based on RPGIV and/or ILE.  However, I was VERY
disappointed to buy one last year (copyright date 1999) called Ready to Run
RPG/400 Techniques, by Julian Monypenny and Roger Pence, and find all the
wonderful examples done in RPGIII!  I've learned to be very cautious with books
that include RPG/400 in the title.

Bob Cozzi had an interesting explanation in the preface to his book The Modern
RPGIV Language (Second Edition):

   "There has been much confusion in the AS/400 world regarding the proper name
   of the RPG programming language.  This is primarily due to many IBM support
   personnel as well as the trade press mistakenly reporting the name of RPGIII
   as RPG/400.  There is not now, nor has there ever been, a programming
   language named "RPG/400."  The current AS/400 RPG compile package offered by
   the IBM Corporation is named IBM AS/400 ILE RPG/400 Compiler.  This package
   contains several compilers for many different RPG languages, including:
        System/36-compatible RPGII.
        System/38-compatible RPGIII.
        AS/400 RPGIII.  There is no "RPG/400" language per se (only AS/400 RPG
        III).
        AS/400 RPG IV.  This compiler targets the native integrated programming
        language environment (ILE).  There is no "ILE RPG" language, only an
        ILE-targeted RPGIV compiler."

This is what confuses me.

He said RPG/400.  I have a book, "AS/400 ILE RPG/400 Programmer's Guide".
Isn't RPG/400 just ILE RPG/400 without using any of the ILE stuff, which
is RPG IV?

Or does RPG/400 designate RPG III?  Or is it simpley that both RPG III and
RPG IV were called RPG/400 and just the first version (RPG III) is called
RPG/400, and the later versions are called ILE RPG or RPG IV?
