Question:

Does anyone have opinions on EXISTING object oriented analysis
tools?  Are there any good ones out there?  Ideally, we would like
to find an OOA tool that supports the Shlaer and Mellor process/
nomenclature as closely as possible.  Also, it would be desireable
for such a OOA tool to run on top of a MS Windows (3.X) dialect of
smalltalk (smalltalk V or 80) so that it could be used in a windows
environment.  Any such thing out there?  Anything close?  

Thanksinadvance for any info,

(please email responses to slewis@hound.att.com...if there is information
to summarize I'll gladly do so)

I wonder if anyone has solved this problem: 

Smalltalk V/Windows, which I gather from this group has lots of bugs.
Version 1.0, Windows 3.0.

Works fine most of the time.  But not infrequently, upon starting a
new session, the environment does not come up again but instead, a 
debug window giving errors from the display classes.  I could recreate
most of the windows -- class changes are still there.  But if I saved
a workspace with a long session, it's gone.  And how to create a new
System Transcript?  Or should I simply give up on the product?  (No,
forget I asked that.  There are enough flams of ST/V on this group already.)

Thanks to anyone who has a suggestion.

My experiences with Digitalk was similar.  They have
pretty lousy technical support even considering that they
are small company.  But wait a minute, for a small company,
making customers should be top priority!

Other problem with Digitalk is that price of their smalltalk
seems to going up with every release.  Latest incarnation of
OS/2 version 2.0 VPM will cost around $1000, which will be 
like pricing structure of Parc Place(ridiculous price of
$3995 for mac/pc).  On top of that, Digitalk's class library
is  as if written by third class hacker.  It is full of
bugs and badly commented (or no comment) codes.

I think Digitalk has totaly abandoned hobbyist and small-business
developers, and has adopted strategy similar to ParcPlace ;
going for MIS/Corporate Market .  This is reflected in their
pricing structure and their heavy emphasis on OS/2 instead of
Window and Mac platforms.

Well there is also C++ (sigh...)

Reply-To: thomas@straylight.med.ge.com
Organization: GE Medical Systems, Milwaukee, WI

Date: 8 Apr 92 13:17:49

Last night I upgraded Windows 3.0 to Windows 3.1 and I thought I would give
my general impressions.

First off, here's my configuration:
	IBM PS/2 model 50Z (286 at 10Mhz with Micro Channel)
	7Mb 80ns 
	110 MB SCSI 
	30 MB internal
	Soundblaster MCA

Sadly, I don't think the performance increase is what it's been
advertised to be.  Sure, the new File Manager is great, but I'm not willing
to put up with the performance degradation of my main Windows apps just to
get it (W4W 2.0, Excel 3.0, Smalltalk V/Windows 1.1).  Additionally, many of
the PCTools 7.1 applications are incompatible with 3.1 as well. 

Smalltalk V/Windows 1.1 encountered numerous "out of memory" errors (even
though the new Program Manager said there was plenty of mem available) which
would cause Windows to terminate Smalltalk (pretty rude when you haven't
saved the image).  I could not open more than 3 CHB's or 2 CHB's and 2
workspaces without encountering this error.  Reframing Smalltalk windows was
an order of magnitude slower and selection of a new class within the CHB
took considerably longer for the methods to appear than under 3.0.

The bottom line for me was I went back to Windows 3.0 for the time being.
Digitalk has version 1.2 in the works (anyone know the release date?) and
hopefully that will solve the performance problems under 3.1.  I'm sure
Excel 4.0 and W4W 2.1 will be out soon as well to address their performance
issues.  Unfortunately, Microsoft has done it again...

"Try filing this into ST80r4.  I wanted to create a simple device for
adjusting variables `p' and `q' between 0 and 1. As p + q = 1, using
two sliders from 0 to 1 is redundant, but I nevertheless felt it would
impress the nature of p and q more firmly on the mind of the user than
a single slider which went from 100% p to 100% q.  So I created two
sliders as PluggableAdaptors on a single ValueHolder model, the put~
and get~ blocks of the latter referring to 1-v rather than v.  It
works.  But if one moves a slider from one extreme to the other by
clicking on the ends of the travel, rather than sliding it through, it
is possible to get both the sliders registering the same value.  This
is surely a bug.  But is it mine, or Parc's ?  Any ideas would
be much apreciated. "

The single-copy educational domestic price for ParcPlace Smalltalk is
US$350. Domestic educational site licenses are US$3500/year (for one
platform; US$400/year per additional platform). The licensed
institution is entitled to redistribute copies to staff and students at
no additional charge as long as the copies are used for educational
purposes (e.g,, a student may not get a free copy and take it away for
use at some for-profit company). For more information on educational
pricing, contact ParcPlace Sales (info@parcplace.com).

If you are a commercial developer of Smalltalk software, you can apply
to become a ParcPlace Partner, which allows you to buy the first copy
of Smalltalk for $350. There are other benefits and incentives as well.
For more information on the Partners program contact John Bruzas
(johnb@parcplace.com).

As of Release 4.0, ParcPlace Smalltalk began using host-system windows.
Keep in mind that the Smalltalk UI predates all the ones mentioned above,
and it took a while to develop a portable solution that used host-system
windows and supported color fully at the same time that other kinds of
improvements were being made to the system.

Carleton has had an educational site license for several years. If you
are unhappy with what they charged you, complain to them. Historically,
upgrades have been offered at prices substantially lower than the list
price of the new version; in addition, customers who had purchased
technical support paid 50% of the upgrade price to get the new version.
Again, for details on pricing, contact ParcPlace sales.

Please don't send me email about prices. Our sales staff have all the
current information and can provide you with more precise information
than I can. THIS IS FAIR WARNING: any email sent to me about prices
in followup to this posting I will happily toss in the bit bucket.

I think U.Illinois has packaged called "HotDraw" which runs on St80R4.
It was originally sold by bye KSC(Knowledge Systems) for $150.00 but
only ran on classic Smalltalk(V2 series).
Also, Smalltalk Express group used to sell bunch of application classes
developed on Tektronix Smalltalk. I don't know whether they are still in
business.
I have no idead how good "HotDraw" package will be in developing commercial
applications.  Most public domain class libraries can be used only in
"toy" like examples.  They don't scale up as complexity of the applications
grows.  They usualy have problems in slow performance, lack of necessary
API, inadaque support of application model space, and printing.
Just to support proper Postscript printing(multiple pages, scale control,
font support) is lots of effort, and is only done by people who are
seriously interested in developing commerical smalltalk applications and
prepared to spend lots of time and effort.

Good luck.

The both your questions are not related directly to OOP, but to a knowledge 
representation scheme. I have developed a knowledge-based system called
DICEtalk
(DICE - DARPA Initiative in Concurrent Engineering at CERC, WVU) and
implemented 
in Smalltalk. I use my novel representaion scheme called percept calculus 
(logical system). The logical formalism is hidden from end users, they use 
simplified English senetences. That sentences when added to a knowledge base 
are translted into logical formulas and their sources are stored in kbsources 
(like Smalltalk sources). All temporary modifications to knowledge base are
stored in changes file (like Smalltalk changes). Formulas during problem 
solving are transformed into metarepresentation objects in the same formalism.
Thus facts are implemented basicly by two classes Sentence (similar to
Smalltalk 
CompiledMethod class) and Rule. Rule class is subclass of Sentence. The both 
classes are supported by the following classes: Attribute, MetaAttribute,
Name, ContextName, MetaName, Estimate, Variable, Path, MetaPath, Term,
Formula, 
Recept, Percept, Metapercept. Hence, all the above classes correspond to the 
knowledge representation model which I use. 

My suggestion: be focussed on a knowledge representation scheme for your system
as an OO model. When the theoretical model works fine then implent it almost 
one-to-one using Smalltalk implemntation as a good example. Your problem
is not 
Smalltalk problem, but AI problem.

DICEtalk current sources: about 800kB of Smalltalk code (wrriten by myself),
about 80 classes. More than 20 knowledge-based engineering tasks were
implemented
by graduate students from Mechanical and Aerospace Department WVYU.
