I just got a ver E HP48 as a replacement for my ver D. And I may have
discovered a strange difference.
On my machine I have a large directory, called MAIN, in the HOME directory.
Occasionaly I will add an item to the HOME directory and afterwards I
use ORDER to put MAIN back at the front: { MAIN } ORDER
The trouble is that I need a lot of free space to do this because MAIN
is so big. Now, just before I sent my ver D away, I could not use ORDER
on MAIN because it had grown too big. I archived the calculator in this
state. When I got the E back I restored my stuff and then discovered that
I could now do an ORDER even though I had very little free space.
I would like to know if any experts out there can comment on this.
It's impossible for me to check this as I no longer have my ver D, but
I am sure enough that this is what I did to be confused.

When had you last archived, cleared, and restored your version D? With heavy
use, the pointer table must get convoluted enough to consume more memory than
necessary, even with the periodic garbage collect. Other HP products have
suffered from "free memory rot". (Any HP Integral owners out there?) A
Master Clear (with no PICT and no spaghettified pointer table) will result in
a net gain in usable memory when your archive is restored -- perhaps enough to
let ORDER work.
Maybe version E calculators have an enhanced ORDER algorithm which requires
less temporary storage? 1/2 :-)

I have to ver E 48 and it frequently requires what seems to be a very large amount of free memory to perform operations like downloads and orders. I assumed this was just the way it worked, until the previous response. Try downloading and see if it works like your ver D 48 did, or if it requires a lot of free memory even to download a small file. I'm just curious to see if there is something actually wrong with ver E.
