zMan accuses me of 'pissiness'.  In fact I posted a neutral technical
exposition of the two packed-decimal formats.  Mr Comstock responded
with, "No, <inaccurate text>".

Now he and others are free use words as they please.  There is august
precedent for doing so.  As Lewis Carroll wrote in TtLG,

"When I use a word," Humpty Dumpty said, in a rather scornful tone,
"it means just what I choose it to mean—neither more nor less."

Still, this forum is [mostly] about zArchitecture machines, and for
them there are two packed-decimal formats.

My own view of the packed-decimal data type was never enthusiastic and
is now very negative.

Storage-to-storage arithmetic was always obscene, but there was a sort
of rationale for its use in some business applications:  HFP and BFP
can yield rounding results that surprise the uninitiated.  Mike
Cowlishaw's DFP has now dealt definitively with these problems, and
any rationale for doing even business arithmetic in anything but DFP
has now also been removed.

The question how many people use DFP in assembly language is one that
I do not really know the answer to.  I should guess not many, but that
is only a guess, and I myself use it routinely.  (It is rather easier
to use in assembly language than HFP, and both it and BFP make
available conversion instructions the absence of which was the chief
obstacle to the use of HFP in assembly language.)

If there is any significant feeling that I should withdraw from this
list too, I am quite willing to do so.  It can survive handily without
me and I without it.
