[comp.sys.ibm.pc] DOS 3.2 and DOS 3.3

whitney@husc4.HARVARD.EDU (glen whitney) (08/25/87)

	I am currently using MS-DOS 3.20, and I would like to know if it is
worth upgrading to PC-DOS 3.3.  Assuming that the price is not a factor, what
advantages and disadvantages does PC-DOS 3.3 have over MS-DOS 3.20?  Any 
physical problems (such as having to reformat a hard disk and many floppies)
are not important to me.   Thanks for your help.

There are a handful of new features which have been pretty well discussed:
being able to "call" batch files (and have them return properly to the
caller), the ability to suppress any line from echoing by preceding with
an "@" sign, some improvements to xcopy (automatic creation of subdirectories
with /S -- unless that's already in 3.2?).

There are two performance features which have not been widely discussed:
FASTOPEN and IBMCACHE.SYS. FASTOPEN is a resident program, which takes a
disk drive as an argument from the command line. I don't know what it does:
buffers the FAT, maybe.

IBMCACHE.SYS is a disk cache, with a configurable size. It may not actually
be part of DOS 3.3: on the PS/2s, it is supplied on the demonstration disk
along with the diagnostics and "Learning the PS/2". It, uh, seems happy on
my AT, though...

And now the down side: the press has had reports of people collecting a
variety of bugs in it. From what I read, seemed like even more than 3.2
and its equal size collection of DISKCOPY patches. But my own experience
with it for the last several months has been great - no problems at all.
Guess you can't believe everything you see in the press ;-)! (please, no
coupons from the Oracle ad!)

There's an article explaining the modifications/additions/... in 
PCDOS 3.3 in "PCResource" vol #6, 9/87.

I got mine in the mail, I don't know if it's on the news stands.

About 3.3 (according to article):
	- supports 720K and 1.44M drives
	- extends HD capacity to 128M by allowing multiple DOS partitions
	     (not quite sure what this means)
	- APPEND to search paths for all kinds of files (instead of just
	     COM, EXE, or BAT)
	- ATTRIB file attributes.
	- changes to BACKUP, RESTORE, DATE and TIME ...

This is just a part of the article.  I don't have any idea how accurate the
article is, I use 3.1 myself.

Good Luck.
