Re: Odd/Even packed numbers. -- MIDRANGE-L

Happy Thanksgiving, you all.

I think that in this day and age, with the CPU power that we take/squander
for granted, this entire discussion is ridiculous.  In the early /38 days,
we set counters in binary, because it made a difference.  Today, I think
that the right thing is to set your data as you need it (from this
perspective), and not waste time thinking about system efficiencies.  The
brute power of the systems tat we use today far overweighs setting the
length or type of fields.
