Subject: Editorial administrativia
Hello,
First of all we need to apologise for the few articles we covered this
week from comp.os.os2.* The reason is simple but regretable: problems
with the disk on which last weeks compilation of news articles was
stored. Everything is back to normal from now on, so next week you'll
read what's discussed during this week.
Next, and finally, we are pleased to mention the excellent new magazine,
of which the first issue is on my desk at the moment, "OS/2 Monthly",
with Joel Siragher as publisher and a.o. Bert Moshier and Timothy Sipple
as column writers, is a 40 pages thick brand new magazine. You can
contact the publisher at the following address: JDS Publishing, P.O. Box
4351, Highland Pk, NJ 08904.

Subject: HELP WITH HARDWARE FOR OS-2
Organization: Waisman Center, University of Wisconsin-Madison
Folks,
I am in the process of ordering a 486-33 MHZ system to be dedicated to SAS
on th OS-2 environment. I have had difficulty finding computer vendors
that know much about the in's and out's of OS-2, especially when it comes
to configuring a system that includes a large hardrive and internal tape
backup (it seems that only a few tape systems have an OS-2 compatible
software package). I need to find some people who are running SAS on a
OS-2 PC.
I am hoping to get the following system, or as close as my budget allows:
486-33 MHZ (maybe 50)
200-400 hardrive (EISA)
5 1/4 and 3 1/2 floppy drives
appropriate internal tape backup
2400-9600 baud modem
twisted-pair ethernet (compatible with Microsoft LAN Manager 2.0 on VAX-VMS)
12-16 MG RAM
My budget is @$5500 for this system, do you think it is possible?
If you could forward System Name, model number, ect it would help me out.
thanks,

Subject: Prolog, PMWord
After one year with PMWord (spent in grief and sorrow...) I had a rather
tough talk with somebody from Microsoft Munich about those loathsome
bugs in PMWord, MS failure to deal with them and future support of PMWord.
In essence, MS said the following:
- There will be a temporary bug fix end of february / beginning of march.
(Personal opinion: A rather unprobable deadline. Several additional
questions, and the date moved more and more to the end of the 1st
quarter 92. And this bug fix still has to be localized!)
- MS promised a final bug fix early summer.
- This final bug fix will obviously be the last thing done for PMWord;
functionality will be frozen at WinWord 1.1 level, there will be no
"Winword 2.0 for PM".
- About same thing for Excel: Do not expect further development, Excel 3.0
seems to be the last thing for PM.
Some postings ago, Rony Flatscher mentioned something about PMWord being
removed from the market. Rony, can you (or any other person)
verify / confirm the above statements?
So much for Micro$ofts OS/2 applications. One other thing, a very
IMPORTANT and URGENT question: Does anybody know a PROFESSIONAL
Prolog-environment for OS/2? We do not need a small public domain tool,
but rather a full blown, reliable development toolkit. Anything in sight?
Cheers!

PC Magazine just published a small assembler utility called "386step.com"
which fits the bill (vol. 11, issue number 3, I think?). On my (B1-step)
386 system with OS/2 1.3, it ran fine in the DOS box. I think it goes
through one subsequent test if the processor is D0 or higher, and that
could conceivably cause a protection violation of some sort, but I know it
works OK for the B1 level, at least. The archive containing this utility
is available for anonftp from such sites as wuarchive.wustl.edu and its
mirrors (/mirrors/msdos/pcmag/vol11n03.zip, probably).
New 386's, both Intel and AMD flavors, are widely advertised in the back
of PC Magazine and other industry periodicals.

I finally got it to run on my SCSI system. I am using an Adaptec 1542B
SCSI host adapter on my ISA based machine. Performance is slow, but I

I am trying to create a Home directory using the os2 server command
line interface.
Reason is because I am creating a command file that will let me
add users, do the file assignments, printer assignments and
assign a home directory without having to go into the NET full
screen interface.
I can create a user, add that user to a group, create an alias
but I cannot do an apply in the command line interface.
I have already looked at the os command line interface help, but
I could not find anything that is helpfull.

You can NOT do an APPLY from the command line (isn't that a pity).
But in your situation (creating a user in batch) you can help yourself
by applying all permisions for groups and making the new user a member
of the appropriate groups. For new directories you are creating together
with the user you have to execute NET ACCESS commands.
Hint : If you are setting up a tree of directories for a user and you want
the whole tree to have the same permission bits there is something that
can help you :
- make the users 'root' directory
- use (serveral) net access statements to set the permissions right
for this directory.
- make the directories under this 'root' directories from a REDIRECTED
disk. (Thus if you use NET ADMIN to execute the command on a server,
the server should have 'used' this disk and you should make the
directory on this 'used' disk.)
If you do it this way the access permissions from the 'root' directory will
be inherited by the newly created directory ||
Hope this help,
Regards,
Dirk

When I went to OS/2 Tools Conference in Fort Lauderdale, one of the
demonstrators was Rick McGuire, who was showing off an Object-Oriented
REXX. He had "Hello" and an "E" workalike editor written in OOREXX
(which is what I'll call it here; does anyone know the official name
for it?). The object-oriented extensions didn't require making big
changes to REXX; I think the biggest change was adding one operator.
(As I recall, it was "~", which stands for "send".) Mr. McGuire said
that the OOREXX was *very* much like Smalltalk, except that it
supported multiple inheritance. (There was a class browser he was
showing off.) The program samples were quite short, as you'd expect
from an OOREXX; I think he said that half the code was to set up the
user interface, so a visual interface builder (a la Visual Basic's)
was a priority. Finally, I think he said that this was a technology
demonstration (which means IBM may never release this as a product),
BUT they were hoping to *bundle* it all in the next version of OS/2
*after* 2.0. (Somebody asked, "You mean, in OS/2 2.1?" He answered,
"If I say that, they'll probably rename the next release 3.0. But the
next release, whatever it's called.")
These are my foggy recollections of what I saw a few months ago.
I hope someone can make additions or corrections to what I've written
above. The OOREXX looked quite exciting, and certainly the price
(free if you upgrade to the next release) sounds great!

Subject: Summary of Datamation Dec 91 cover story (long)
Date: 29 Jan 92 06:33:01 GMT
Organization: National University of Singapore
This is a summary of Datamation article "Inside the New OS/2". It is on
p26-30 Dec 91 issue. I obtain this from my IBM SE.
----------
This is a glowing review of OS/2 2.0 based on quotes from some of the
20,000 users of beta versions and Datamation's own testing. The article's
objective is to answer the question "Is OS/2 2.0 really, as IBM boasts,
better Windows than Windows, better DOS than DOS and better OS/2 than
OS/2?". The answer is a reassuring "Yes!"
Quotes from beta users:
o Paul Ratner, assistant VP of IS at Metropolitan Life: "It's what
OS/2 1.3 should have been. It lets us solve a great many of our
users' different problems with one operating system."
o Gary Serif, manager of applied technologies at the IS arm of
Huntington Bancshares Inc: "Lots of people have seen it and are
coming to us and telling us 'We want it now'".
o Sheldon Laube, national director of information and technology at
Price Waterhouse, where he support thousands of true-blue Windows
3.0 users: "Experienced DOS users take it as a given that Windows
doesn't always work - the average user reboots regularly. Clearly
DOS doesn't cut it as an operating system."
Datamation's review:
o In what ways does OS/2 2.0 run Windows better than Windows?
. No waiting while files are printing
. Double fast data downloading
. Up to 64 virtual megabytes per Windows session
. Unbreachable memory protection between Windows, DOS and OS/2
. Up to 240 Windows sessions can run simultaneously, each with its
own private group of Windows Applications, "something you won't
likely see Windows ever be able to do under DOS."
o In what ways does OS/2 2.0 run DOS better than DOS?
. 633 kilobytes of conventional DOS memory for each of 240 DOS
applications you can run at one time
. Gives DOS extended memory applications (e.g. Lotus 3.1) up to 512
MB each.
. Only 3MB of physical memory required to do this
o In what ways does OS/2 2.0 run OS/2 better than OS/2?
. Multiple DOS sessions
. Windows
. 32-bit memory management
The IBM development team is described as a "handful of MTV-generation
developers - ages 26-28" who "worked 60 to 85 hours per week, living on
Diet Pepsi, Dorritos and rock & roll from dawn to dawn." IBM'ers quoted:
o Shon Saliga, manager of the OS/2 2.0 development team in Boca
o Lori Brown, project director for the OS/2 2.0 Workplace Shell
o Darren Miclette, software engineer
Shon and Lori are pictured on the cover of the magazine as well as in
the article. There is also a picture of the IBM Windows development
team.

Subject: Re: Will Lan Manager 2.1 run on/with OS/2 2.0?
Organization: Kingston Polytechnic
Date: Fri, 31 Jan 1992 10:30:33 GMT
I think the main reason as to why LAN Manager 2.0/2.1 or the new IBM LAN
Server 2.0 Advanced package will not run on a server running OS/2 2.0 is
the HPFS386 driver. I believe that this driver was specially written to
take advantage of 386 machines for speed reasons and that this driver is
not compatible with OS/2 2.0. However, if you don't use the HPFS386 driver
you may find that LAN Manager/Server will run under OS/2 2.0 but you lose
the speed of HPFS386 and the local security option on the server as well
as possibly some of the other features, which is basically what the IBM
LAN Server 2.0 Entry package is, and this IS supported on OS/2 2.0.
So if you want all the fancy features you're stuck for the time being with
OS/2 1.x. My guess is that if anyone is going to provide these features on
OS/2 2.0 it will be IBM with IBM LAN Server, which after all is just LAN
Manager with modifications. So you might want to consider switching to IBM...

Actually, the official MS stance, as I understand it, is that Lanman *client*
will work under OS/2 2.0 after GA. This is borne out by the Lanman 2.1 beta,
which came with a 6.149-compatible client.

Extracted from the HELP DISKCACHE screen in 6.177
Specifies the number of blocks of storage to allocate for control information
and for use by the disk cache.
DISKCACHE = DDDD n DD>DDDDDDD>D>DDDDDD>D>DDDDDDDDD>DDDDDD
@D ,LW DY @D ,T DY @D ,AC:x DY
Type this command in the CONFIG.SYS file; do not enter the command at the OS/2
command prompt.
The disk cache allows a portion of the system storage to be used as an
additional hard disk buffer. DISKCACHE
speeds up application programs that read hard disks by keeping hard disk data
frequently accessed in a cache buffer.
When an application program requests hard disk data that is already in the
cache buffer, the disk cache sends the
data directly to the application program. This method of accessing data is
much faster than if the data had to be read
from the disk each time.
Specifying this statement increases the speed of your system. However, when
you increase the size of your disk
cache you also decrease the size of available storage. For this reason, you
may want to experiment with the number
of blocks you specify to get maximum performance. The recommended disk cache
sizes should be based on the
amount of memory that is available in the system, not the disk size.
General DISKCACHE parameters size guidelines are as follows:
o Systems with 2MB to 3MB of physical memory should use a disk cache size of
64KB.
o Systems with 4MB to 5MB of physical memory should use a disk cache size of
192KB.
o Systems with 6MB or more of physical memory should use a disk cache size of
256KB.
o In most situations a threshold size of 32 is recommended
The amount of storage required for control information is determined by the
total size of one or more hard disks.
When the amount of storage you specify in the DISKCACHE statement is not
available, the system displays an error
message. When the amount of storage you specify in the DISKCACHE statement is
not sufficient to support the total
hard disk size, the disk cache does not work. The disk cache is allocated at
system startup, and there is no dynamic
adjustment of its size.
It is recommended that the threshold size be set at 32 unless the software
product you are using is disk intensive and
the manufacturer supplies information on the block size required. If the block
size is defined in terms of byte count,
divide the byte count by 512 and round up the quotient to the nearest whole
number to determine the threshold
value.
The disk device driver for the Personal System/2 Models 55sx, 65, 70, 80, 90,
and 95 provides direct-access storage
disk-cache support for use with hard disks. This device driver controls
operation of the cache, which is allocated by
the system and taken out of storage above 1MB. The cache is run as a
write-through cache to maintain data integrity.
Sectors passed to the disk device driver for writing on the disk are guaranteed
to be written out to the disk on
successful return from the device driver.

My personal impressions about LA version :
1) With 4 Megs RAM is painfully slow, not to compare with windows.
2) Dos boxes are incredible. Fantastic. Great !!!
3) Where is protection ? I can crash OS/2 at will.
Try this BASIC program in a dos box :
DEF SEG = 65535
FOR I = 0 TO 65535
POKE I,0
NEXT
It locks my machine to death !!!
If it doesn't lock yours try changing segment value.
4) WPS is graphically perfect.
5) Windows is surely better, you get more performance given the same machine.
If I buy 4 Megs RAM I could get same speed as Windows, but where are
advantages ? I can see no protection at all.
Maybe OS/2 is better than Windows, but you have to spend too much money,
and you don't get much more.

Subject: 32-bit demo version of DeScribe for OS/2
Date: 5 Feb 92 10:23:02 GMT
Organization: Technische Universitaet Muenchen, Germany
Yesterday I received a new version of the 32-bit preview of DeScribe 3.0
for OS/2 2.0 6.177 and it works quite well now.
It is really faster than the 16-bit version running under 2.0 too.
Loading a 60 page document and repaginating it (by moving to the end of
the document immediately after loading it) took only 9.5 seconds while
the 16-bit version needs 18.5 seconds for the same work. DeScribe wrote
the general speedup would be about 30% and up to 100% in some areas (I
guess I hit such an area).
[Note for people not familiar with DeScribe: after loading a document,
the program normally starts a background thread which repaginates the
document while the user already starts working at the top. But when
pressing Ctrl-End immediately after loading, the user has to wait until
this thread has finished. However, if the document was saved with the
cursor at the end of the text, DeScribe places it there again after
loading immediately, without repaginating it first, because it
apparently stores the previous pagination too. This test above was just
one of the few situations coming to my mind when trying to find an
operation which causes the user to wait at all. Another one is import of
text or graphics, but this is disabled in the demo.]
Also, it appeared to me that the 32-bit version needed significantly
less memory than the 16-bit version (almost a whole meg). I don't know
if this is caused by the disabling of im/export filters and
speller/thesaurus because I thought that they are loaded on demand only
in the regular version too.
So even regular text processing users can really benefit from using
32-bit OS/2 apps instead of 16-bit apps.
