Rather sloppily, I didn't pick up the importance of this remark until...
In article <3BD48D50.21C4D907@xontech.com>, Phillip David wrote:

Let's just spell that out again in words of one syllable:
HDF5 is NOT the next version of HDF4.[1] Apart from the facts that they are
both file formats for storing large wads of scientific data, and
that they both come from NCSA, they are totally and utterly different things.

And he is 100% correct. Not a lot I can add to that, except to note that
over in the thread "Message From RSI VP of Engineering", Struan Gray
spake thusly:

Now, NASA's EOS program is (a) a Large IDL customer, and (b) is actively
switching from HDF4 to HDF5. Do I have to go on?
