First of all your %ages are way off.  In the days when the compilers were
sold separately, then for every 6 RPG compilers sold IBM also sold a COBOL
compiler.    However, most COBOL shops _also_ have an RPG compiler, due to
most packages being written in RPG.  The number of pure COBOL only shops is
probably about 2%.

Second - IBM is still selling 400s as replacement systems for mainframes
(particularly VSE systems) and they are mostly COBOL.  Also many of the
existing COBOL shops are _huge_ customers such as AllState.  I doubt that
IBM wants to tick them off.

Third - unless things have changed recently, COBOL is required to be
available on the box before you can even bid on many government contracts.
To drop the compiler would be to abandon those business opportunities.

IBM (with the exception of a few dedicated types in Toronto) would much
rather that RPG curl up and die.  Besides - while the compiler will port
easily (it is written in C and has already been ported to Windows for CODE
and VARPG) the _functionality_ of RPG is heavily dependent upon OS/400
features.  Think display files, subfiles, printer files, a database that can
be accessed via "flat file" I/O OR SQL, etc. etc. etc.  You can't port RPG
without those features.  VARPG only works because it connects to a 400 to be
able to use them!

I'm not convinced.  While I don't take everything that Dr. Frank says as
gospel, LPAR, Linux and PACE demonstrate that OS/400 is capable of managing
multiple environments in the same box.  I would say that the absence of
OS/400 under AIX is a good sign and not the negative that you have painted.

At last a sentiment I can agree with!!  Hey - you did say you wanted
dissent!  <grin>
