The AS/400
version arose from different roots and shares only the external interface
with the UDB version.  We can thank the leadership of Bill Davidson and
Larry Youngren for that implementation - there may have been other
more-senior guidance but, aside from Dick Bains and Glen Henry, I don't
know
those names.

If the AS/400 database product is superior to another one on my list (and I
do not say that it is or is not), it is because DB2/400 runs on only one
platform and is therefore easier to test.  As far as I can tell, that is
the
most important objective difference between them.  Other differences exist
but, in my opinion, they are less important or subject to change with
funding or time.

This reply got out of hand, sorry.

Richard,

In my semi-rare copy of the 1980(2nd edition)  "IBM System38 Technical
Developments"  manual  (Which was a series of articles by various authors
on the uniqueness of the machine) ,   The following chapters/articles
were

System/38 data base concepts -   C.T.Watson,  F.E.Benson,  P.T. Taylor

File and Data Definition facilities in System/38 - C.D. Truxal and
S.R.Ridenour

File Processing in System/38 -  R.O. Fess,   F.E. Benson
---------------------------
I remember seeing the "Bill and Larry" show in '86 at COMMON at a session
on  "Sys/38 Internals"      An intense session, one of the best I ever saw.
Bill told a story of a call he got on a Monday  from a guy with a 8-meg
sys/38 who started a re-org of a file with hundreds of thousands of records
on a Friday and it was still running on Monday.    Bill said  "Don't  touch
it !"   It finished on Weds.     So he said "Be careful out there,   this
stuff sometimes can take calendar time"

I thought it was funny.   (Calendar time)


Bains and Henry were/are giants.    G.G.Henry  I think left disgruntled and
took on the PC-RT project in Austin(?)  the "Proto-RISC" stuff.

BTW,   Henry co-wrote the "Sys/38 - A High-Level Machine"    article in my
manual along with  the "Introduction to IBM System/38 Architecture" .

Thanks for reminding me and letting me reminisce.

John Carr
