According to The Dostalk Scrapbook, there are 3 official (as in Apple made
'em, I think) versions of DOS 3.3. PEEK (46725) supposedly tells you which is
running:
165: oldest (1980)
186: better (January 1, 1983)
182: latest (?)
I remember one had something to do with the way text files are handled.

The second version would be the IIe release ("DOS 3.3e") which contains yet
another APPEND patch, and an additional bit of code which shuts off the 80-
column firmware during boot. That version comes on a new System Master which
uses the LOADER.OBJ0 program to fast-load INTBASIC (or FPBASIC), and a revised
"HELLO" program which displays the "BE SURE CAPS LOCK IS DOWN" reminder on a
IIe.

One big problem with DOS 3.3e (and, probably, any later versions) is that
it uses some memory in the DOS area which the 1980 release leaves alone. This
means it can not be safely patched with Beagle's "Prontodos" speed-up mods.
With DOS 3.3e, you get an APPEND patch (which turns out to introduce a new
APPEND bug), a IIe display frill, and a DOS which is _much_ slower than the
1980 DOS 3.3 patched for Prontodos.

018- How can I find out the address and size of a BLOADed
DOS 3.3 file?
After you BLOAD a file, you can use the following command to find out the
exact length of the file you just BLOADed:
PRINT PEEK(43616) + 256 * PEEK(43617)
Use another PEEK to find out where it was loaded:
PRINT PEEK(43634) + 256 * PEEK(43635)
The value displayed is the load address of the binary file.
