ENTRY 0 - Rumors and other miscellaneous...

Several companies are using Tcl or Tcl/Tk in their products but do not
advertise that fact.

It is rumored that the following computer vendors may be using tlc/tk in a
future version of some of their management tools: SCO, Digital, Cray.

It was stated at the Spring 1994 DECUS Symposium in New Orleans by a
speaker from OSF that the management tools "DCE Shell" that is part of
DCE Version 2.0 is an extended tcl/tk shell. The speaker did not know if
dynamic loading was present nor what extensions are present.

In addition, numerous companies are using Tcl to automate regression
testing. In essence, they are using the framework developed by folks at Sun
that is used to test the Tcl implementation. Take a look at the files in

Tcl/Tk and its archive have begun to appear on CD-ROM archives. One
such archive was made by Dr. Dobb's Journal.

A customer of Itasca Systems created an initial Tcl interface to our
ODBMS using the C API as the underlying transport mechanism. He did not
complete the work, but did have some miminal functionality implemented.
This code is included is as a freeware ObjectShare library that is shipped
with each product. If someone is also interested, Itasca Systems has said that
they could easily send it to them. Note that this is not a supported product,
nor is it complete.

ENTRY P1. - Use of TCL/TK for Computational Fluid Dynamics

Usage: Computational Fluid Dynamics Applications
Company: ICEM CFD Engineering, Berkeley CA
Contact: Wayne A. Christopher

We have been using Tcl/Tk extensively since 1992 for front-ends to
computational fluid dynamics (CFD) systems. We currently have two main
products. The first is ICEM CFD, a general purpose front-end that includes
a CAD system, several mesh generators, and interfaces to numerous flow
solvers. The second is ICEPAK, which is specific to electronic cooling

In ICEM CFD, Tcl/Tk is used for several components. The first is a
"manager", or a graphical shell that is written entirely as a wish script and
ties together over 100 component programs, manages the files they use, and
gives the overall system a more unified look and feel. The second is Leo,
which is a grid visualizer that is partly written in Tcl and partly in C++, and
allows the user to examine and modify computational meshes that are
potentially very large. The third is a CAD tool, P-Cube, which is a large
program mostly written in fortran, that has some rather tricky qualities
that made retrofitting a Tcl/Tk interface an interesting task, especially in
the area of event loops. Finally, several mesh generation tools have separate
Tcl/Tk interfaces that run as pure wish scripts and communicate with the
"real" application using pipes.

ICEPAK, which was developed in collaboration with Fluid Dynamics
International, was designed to be a very application specific tool. It
recognises electronic cabinet components such as cooling fans and printed
circult boards and handles each of them specially. There are three
components to this system: the front-end/postprocessor, the automatic
hexahedral mesh generator, and the solver. Only the first was written with
Tcl/Tk. The code specific to the front-end includes about 35K lines of Tcl
and 35K lines of C++, and some rather large Fortran components which,
fortunately, another group maintains.

Our experience with Tcl/Tk in the CFD environment has been very positive.
The key to using Tcl with large data sets is to ensure that only data that
remains small is manipulated at the Tcl level, and that all other data is
passed around using handles or pointers to the lower level. Industry
acceptance has been very good, both due to the ease of fast modification and
customization and also to the high quality of the interfaces that can be
created. It also helps that most tools previously available for mechanical
engineers have had rather unfriendly GUI's.

packages: Framemaker, Interleaf, WordPerfect Development environment:


The code generation of all Westmount products is based on parsing
diagrams and generating code from that. This conversion is written in C++,
the generation in TCL. The advantage of that is that users can adapt the
code generation themselves, which is even more interesting because they can
also extend the diagram definitions.

We have extended TCL with some features which converts diagrams from
the repository into an internal datastructure (model) which can be accessed
from within TCL.


ENTRY P3. - Supervisory Control and Data Acquisition (SCADA) by
Computerized Processes Unlimited, Inc.

Usage: Supervisory Control And Data Aquisition (SCADA)
Company: Computerized Processes Unlimited
Contact: Gerald W. Lester

Computerized Processes Unlimited, Inc. (CPU) is an independent consulting
system integrator. The company serves oil and gas, energy and other process
industries. CPU's staff has expertise in requirements analysis; and design and
implementation competencies in process, electrical,mechanical,
instrumentation, software, and control systems. The company's product is
knowhow in the technical areas it has targeted.

CPU has embraced Tcl/Tk technology and made it the basis for its SCL
System Integration Technology. In combination with Hewlett-Packard
Company's RTAP/Plus applications enabler product, CPU has engineered
and delivered powerful SCADA systems.

RTAP/Plus is not a complete SCADA package. A user must furnish
applications (including the GUI) to build an RTAP system. CPU's SCL
brings all of RTAP's API (i.e., call interface) up into Tcl as Tcl commands.
The GUI and application programs are written in SCL (system
configuration language)--Tcl/Tk with CPU's RTAP extensions. This
technology has been implemented and delivered on the distributed
client/server model.

The most ambitious application of this technology is for an oil and gas
production platform in the Gulf of Mexico. Shell Offshore Incorporated's
tension-leg platform, Auger, was designed to produce 40,000 barrels of oil
per day and 150 million cubic feet of gas per day. This $1.2 billion facility
began producing oil and gas in April 1994. The monitoring and control
system integrates numerous state-of-the-art technologies--in excess of 12
workstation-class computers on an ethernet network, communicating with
over 40 programmable logic controllers, in a distributed data base
environment, using both copper coaxial and fiber optic cable--in an open
system architecture. The system is connected with all aspects of facility
operation: production, drilling, utilities, and marine operations.

CPU's Tcl/Tk efforts for SCL System Integration Technology and Auger
have resulted in excess of 250,000 lines of Tcl/Tk code, the largest known
Tcl/Tk project to date.

ENTRY P6. - SYSTEM 9 Geographic Information System (TM)

Usage: GIS
Company: Unisys Canada Inc, GIS Division
Contact: Alex Lee

SYSTEM 9 Geographic Information System (TM) is a workstation based
commercial software developed by the Unisys Corporation. It is being used
worldwide in facility/utility management and mapping applications. Some
of the SYSTEM 9 functionality includes spatial data capture and
management, raster image processing, graphic data display and plotting, and
client/server distributed processing. SYSTEM 9 currently runs on Solaris 1.x,
2.x, HP-UX 9.0, and IBM-AIX 3.2 platforms operating in the UNIX/X

With the increasing diversity of end user applications, SYSTEM 9
architecture allows users to build custom applications to meet specific
requirements using the Application Tool Box (ATB)(TM) module. The
ATB module supports Unix style commands that interface with underlying
SYSTEM 9 functionality. In addition, a C API is also available for
applications written in the C language.

Currently, the Korn Shell (KSH)(TM) is being used as the scripting
language for building applications. The majority of SYSTEM 9 customers
are using KSH for customisation. The C API is used only by a few who
require performance and have in-house 3GL programming support staff.
One of the drawbacks of KSH is performance and a lack of GUI support.
The Windowing Korn Shell (WKSH)(TM) from AT&T may fill the GUI
gap, but the complexity of Xt/Motif syntax is beyond the comprehension of
many of our customers (who are not trained programmers). This has led to
the requirement for an extensible command/scripting language that
supports GUI, easy to use, extensible, fast, and syntactically like KSH. This is
where Tcl/Tk fits in.

Our plan is to use Tcl/Tk as the front-end command parser/dispatcher
which operates in sync with special tasked servers across the network. This
fits in nicely as the client side C API of ATB is already in a format that can
be easily integrated into Tcl. However, new protocols will be needed to allow
servers to communicate with the Tcl/Wish interpreter or vice versa. The
client/server model reduces the size of the interpreter and yet maximizes the
processing power of networked machines.

We expect to use Tcl/Tk as a common programming language for both
internal core development as well as end user customization. Using Tcl to
implement base functionality hopefully will give us a better turn around
time in both development and field support. We also plan to establish
guidelines and standards for building Tcl/TK applications to ensure
consistency across our products.

At time of writing, a prototype Tcl/Tk interpreter with a subset of SYSTEM
9 functionality is completed for internal evaluation. Also, the first draft of
the Tk style guidelines is being reviewed. The tentative customer ship date of
this product is around end of this year.

We understand that the SYSTEM 9 GIS extension will not be public domain
software, but by adopting Tcl/Tk in our product will help extend the Tcl/Tk
horizon into the commercial arena, especially the ever expanding GIS


P7. - {*filter*}term - a Networked 3D OS for PCs

Usage: {*filter*}term - a Networked 3D OS for PCs
Company: {*filter*}term Pty Ltd
Contact: Michael Snoswell

{*filter*}term is a 3D type of operating system, a bit like a multi-user flight
simulator where everyone can log into central servers via modems from
their PCs. The servers can also be connected together to form a single huge
{*filter*}space. All objects within the environment are user programmable,
using Tcl, extended by about 150 functions for object manipulation, file and
message handling, user interaction, environment control, networking,
security and general administration.

Tcl is used to write applications within the environment. Such applications
currently include an artificial life demo with growing, breeding and evolving
plants, herbivores and carnivores, a 3D file system manipulator and a
multi-user shooting game.

The system is currently in beta test. The server runs under QNX, the PC
client under MSDOS (compiled with Watcom) using a slightly modified
version of Tcl 7.3 (mainly for security reasons).

Usage: UNIX System Administration
Company: Parallelograms
Contact: Terry Coley

Telephone: 818 577 5515
Fax: 818 577 5515


Nanny is a Tcl-based CPU-time balancer for UNIX compute servers.
Nanny automatically balances CPU-time between users and groups of users
on single and multi-processor UNIX computers by periodically adjusting
relative process priorities. Nanny can also be configured to automatically
give high priority to a console user. Tcl scripts are used to configure Nanny.
The package includes a Tk script which graphically displays the CPU-bound
per user load for any Nanny host in your network.

All Parallelograms products are enhanced with TCP/IP communications
Tcl commands which are an extension of Kevin B. Kenny's tclTCP package.
Included in the extensions are timers for creating applications which run
periodically. Source code for this enhancement is freely available and
distributable, with or without a license of Parallelograms products.

Contact: Terry Coley

Telephone: 818 577 5515
Fax: 818 577 5515


The Kernel Information System allows rapid creation of
platform-independent UNIX process management tools. KIS implements a
single (multiple option) Tcl command which provides UNIX kernel
information for any KIS host on your network. With just a few lines of
script, you can query the state of processes throughout your network. KIS has
powerful filtering capabilities to let you select only those processes of
interest. For example, the filter "RSSIZE > 5MB &&
delta(CPU)/delta(TIMESTAMP) > 10%" will select all processes with a
resident memory size greater than 5MB and using more than ten percent of
CPU-time since the last scan. Perl users can also use the socket() function to
obtain information from any KIS server.

Parallelograms maintains a growing library of freely distributable KIS
application scripts.

All Parallelograms products are enhanced with TCP/IP communications
Tcl commands which are an extension of Kevin B. Kenny's tclTCP package.
Included in the extensions are timers for creating applications which run
periodically. Source code for this enhancement is freely available and

Usage: Scripting Language for Telebit NetBlazer
Company: Telebit
Contact: Bill Webb

Telephone: 1-800-Telebit
Fax:       408-745-3810

Telebit NetBlazer

Telebit uses tcl (actually the non-Unix subset) as a scripting language for
their Wide area router product (the Telebit NetBlazer).

This allows customers to implement extentions to the NetBlazer in a
convenient standard scripting language rather then by adding extentions to
Telebit's existing interactive command language.

Among other things that have been done with tcl scripts are to provide a
global command that implements pattern matching on existing commands
over users, files, routes, dialouts, etc. etc., and new ease-of-use scripts that
allow users to avoid use a menu-like interface to configuring their

Telebit customers have also implemented their own scripts for their own
needs that range from a few lines of code to hundreds or thousands of lines.

SCO Visual Tcl

SCO is distributing pre-release copies of SCO Visual Tcl at its SCO Forum
'94 this week on the campus of UC Santa Cruz in California. It is now
available on the SCO Skunkware 2.0 CD-ROM as well as the SCO on-line
technical library (TLS) for anonymous uucp/ftp. SCO Visual Tcl is a new
technology that extends the Tcl scripting enviornment with Motif
1.2-specific commands.

"SCO Visual Tcl" is the SCO trademarked name for the revised version of
the SCO technology formerly referred to as the "Widget Server." The new
SCO Visual Tcl has been reworked to

 o support a hierarchical, dot notation style of widget naming,
 o provide more control of the Motif environment to the programmer,
 o enhanced widget callback support.

The goals of SCO Visual Tcl are to

 o provide a rapid environment to develop Motif and Character
   applications simultaneously, with a feature set highly-driven by the
   needs of systems management, and
 o make it simple to graphically extend the SCO Open Desktop
   environment via an easy-to-use scripting environment.

SCO Visual Tcl will be the graphical interface technology-of-choice for
SCO's next generation system administration tools. While the primary
purpose of SCO Visual Tcl is to simplify creation of system management
interfaces, "Vtcl" is also quite capable of satisfying the needs of
light-to-mediumweight general Motif application development.

Key Features of SCO Visual Tcl include...

 o Event-driven (callback) environment
 o Display engines for both Motif 1.2 and curses-based Character Motif
 o Point Help, Context-sensitive Help, and Status Line
 o Convenience Function Library
    o includes ToolBar, ComboBox, Spin support, and assorted
      widget combinations (e.g. text fields with labels or titles)
 o DrawnList Widget (icons in list widget)
 o Window Manager controls
 o Relative-positioning geometry management
 o Based on Public Domain U.C. Berkeley Tcl 7.3b
 o POSIX-specific and other extensions
    o e.g. fcntl, select, nice, kill, sockets, fmtclock, trace
 o Package library support, as well as vtcllib.a and header files for those
   wishing to extend the Vtcl interpreter with C-based routines.

IXI, a subsidiary of SCO, is planning to port Vtcl to other major Unix

SimCity, the original award winning city simulation game from Maxis
Software, now runs on powerful Unix workstations with X11! DUX's
implementation of SimCity for Unix was awarded product of the year 1992
by Unix World in the January 1993 issue, and reviewed in the April 1993
issue. Now it's souped up, works with standard X11 servers, and even supports
networked multi user collaboration! Multi Player SimCity is designed to be a
fun cooperative educational experience!

SimCity is a colorful animated interactive system simulation game,
providing a set of rules and tools for planning and building a complex
dynamic simulated city. Several people on different X11 workstations can
participate in the same city, cooperating and coordinating their actions
across the network.

Working together, you can zone land use, hook up the power grid, build
roads, bridges, parks and stadiums, raise taxes, and even summon disasters,
causing the city to grow and thrive, or crumble and die. It's a creative,
entertaining way to develop your political skills!


SimCity runs on Silicon Graphics Irix, SPARC SunOS, and other Unix
workstations. You can play it locally or over the network on most 8 bit color
or monochrome X11 displays, like NCD X terminals. And you can hear it on
standard sound devices, and NCD's NetAudio server.


SimCity supports but doesn't require the X11 shared memory and shaped
window extensions, and a local sound device or NetAudio server. And you
can turn off the sound so your boss doesn't know you're playing!


Multi Player SimCity for X11 sports the Motif look and feel, implemented
using the efficient TCL/Tk toolkit. It features multiple city editors and maps
with overlays, fast colorful animation, engaging sound effects, easy to use pie
menus and direct manipulation interaction, simultaneous multi player
editing, communication and annotation facilities, and voting dialogs for
group decision making. It includes eight challenging scenarios and a library
of interesting cities.


Multi Player SimCity is available directly from DUX Software, and via
anonymous ftp from (, in the directory
"vendor/dux/SimCity". You may freely copy it, and play the fully functional
game in "demo mode" on one display without a license, but the city melts
every 5 minutes. If you enjoy SimCity, you can buy a license over the phone
by credit card, without leaving your seat! A single player license lets you save
and restore your cities, and play for as long as you like on one display; a multi
player license lets you play SimCity with your friends over the net!

General Description

Sibylla is an application development framework for World-Wide Web
based application. Sibylla supports interfaces towards BasisPlus from
Information Dimensions Inc., towards World-Wide Web (WWW) and, in
general, towards applications running on the server computer. Sibylla allows
the access, through Internet or TCP/IP LAN, to data stored in a BasisPlus
database or managed by a server-side application.

Sibylla lies between the information sources (e.g a database ), the user
application and the WWW server. The user application is a custom
application and defines, for each application, how the user can interact with
the information sources.

Purpose of Sibylla is to permit the access to information sources through
WWW. Information can be organized, on the server side, using a DBMS (as
BasisPlus) or through indexed HTML files, or getting data from a server
application actived with parameters sent by the client. The server
application is completely general and the duty of the user application,
developed with Sibylla, is to manage the input/output between WWW and
server application.

Software, developed with Sibylla, is organized in simple modules which
allow rapid application definition and prototyping together with simplicity
in integrating external applications. Sibylla is a set of C functions which
extends the official Tcl/Tk libraries allowing, from a Tcl script,
manipulation of WWW related standard and functions as well as databases
and server applications.


Sibylla architecture has been design in order to guarantee completely
portability of user application among different hardawre and O.S. where
Sibylla is available. Sibylla Ver 1.0 e 2.0 are available for Unix (SunOS
4.1.3/Solaris 1.1.1, HP-UX 9.0, OSF1 1.3) for VMS 5.5.2.


Version 1.0

Version 1.0 is organized in a single read module with all Sibylla functions.

Version 1.0 functions allow:

 o communication with an HTTP server according with the CGI
 o URL manipulation
 o management of HTML documents ripetitive parts.
 o BasisPlus access
 o query building and sending to BasisPlus
 o to activate server side application programs and to pass them
   parameters received by the WWW client
 o to build reports merging queries and server application outputs

BasisPlus conventional and continuos record can be accessed in Ver. 1.0.

Sibylla ver. 1.0 will be released in December 1994. A user application using a
Beta version of Sibylla will be available on the WEB by the end of
November 1994 at Centro Interfacolt` per le Biblioteche, Bologna, Italy.

Version 2.0

Sibylla ver. 2.0 will be available in Summer 1995. This new version will
contain a write module able to manage data input in BasisPlus records and
will permit access to BasisPlus sectioned record. Moreover BasisPlus non
standard document format will be managed by Sibylla and viewed on the
WWW client using local browser. Http functions able to manage http
protocol requests will permit multiserver-multiplatform information system
development. Interface toward ORACLE database is under evaluation.

System Architecture

The simplest system architecture which uses Sibylla is composed of a WWW
server, the Sibylla package, the information sources, the user application(s)
and one or more WWW client. On the server computer where the
information sources reside (the BasisPlus database, indexed HTML files,
general applications) there is the Sibylla package too. The generic WWW
client resides on another Internet (or TCP/IP ) connected computer. On the
server computer there are the scripts, which constitute the user application,
which defines how a user can interact with the information sources. For
example we want the user prompted first with a static HTML home page
which explains the service offered; then an HTML form can be selected to
query the information system. The form data are managed by Sibylla and
sent to the database or to any other information source kernel which
contains the data required. Finally the user application get the data returned
by the information source, format and (eventually) analyze them and send
back all things to the client. Navigation (e.g the hierarchy of html files
which defines how the information have to be presented to end user) is
defined within the same user application which handle the user query. From
the end user point of view Sibylla is completely transparent. The end user
simply queries the information system and navigates through the
dynamically generate HTML files. The end user has a single information
view and do not have to take care of where the information is actually
stored or how it is organized.

XESS - The Advanced Spreadsheet For Business and Technology

 o Comprehensive functions, flexibility, and speed
 o Real-time, protocol-independent data exchange and control of
   remote clients
 o Presentation-quality color reports and graphs for business, science,
   and engineering
 o Easy Integration with other client/server applications
 o C and FORTRAN programming interfaces available

As the first spreadsheet designed specifically for X Windows and Motif,
XESS has always been a star performer. Its flexible environment
accommodates complex calculations and data manipulation. Its extensive
computational and graphical tools are ideal for both financial and
scientific/engineering applications. And thanks to the unique XESS
Connections API, this spreadsheet easily integrates with other applications
for seamless sharing of data and control.

Created for the demands of highly technical workstation computing, XESS
provides a full range of mathematical, statistical, financial, matrix, and
string functions. Yet it handles these complex calculations with the ease of a
familiar spreadsheet format with attractive screen displays and an intuitive,
point-and-click user interface.

XESS is simple to learn, but well-equipped to handle sophisticated

 o Financial trading
 o Statistical analysis
 o Process control monitoring
 o Interactive product design
 o Laboratory experimentation
 o Quality assurance testing
 o Scientific visualization


In addition to traditional spreadsheet tasks, XESS supports all arithmetic,
Boolean, and logical operators available in the C programming language.
XESS has a wealth of functions for complex engineering, scientific, and
financial calculations.

With XESS's embedded tools, you can enter and recalculate matrix, vector,
and Fourier transform operations as easily as other spreadsheet functions.
You can use constraint expressions to indicate when cell values are outside
desired boundaries or use goal-seeking to solve a system of equations to a
desired value. XESS also includes powerful tools for searching, sorting, and
data visualization capabilities.

Enhanced Graphics

XESS puts presentation graphics at your fingertips. Build basic graphs with a
single selection and mouse click, use colors and shading to emphasize
differences, then print the graph or export it to your favorite publishing

You can see your data in the form you prefer, from simple pie chart to
complex 3D surface, or both at once. As your data changes, your graphs
change automatically, and dynamic annotation highlights important aspects
of the results. View your graphs in separate windows or place them on the
sheet with your data.

Real-Time Client/Server Integration

XESS's most compelling feature is its ability to adapt to a changing world.
While most spreadsheets capture only a snapshot in time, XESS reflects live
action, sending and receiving data and commands from other client/server
programs -- even on other computers -- and automatically recalculating
the affected worksheets.

XESS runs under Motif on UNIX and OpenVMS workstations. This
operating environment is especially valuable for engineers, scientists,
financial traders, and other professionals who require powerful computing,
ease-of-use, and hardware flexibility.

XESS users can transfer data between spreadsheets running on different
computers. And with the Connections API toolkit for C and FORTRAN,
other applications can transfer data into or out of an XESS spreadsheet as
the data is calculated. Your XESS spreadsheet can display a real-time
summary of data originating on networked computers in other buildings,
cities, or countries. And applications can control all aspects of the

While other programs fade away, XESS remains a bright star in the
client/server universe. With its smooth touch, powerful technology,
impeccable graphics, and total flexibility, XESS defines what a spreadsheet
should be.

TipTop Software Ships TipTop Version 1.5

Bethesda, Maryland, December 22, 1994 --- TipTop Software is proud to
announce that TipTop v1.5 is now shipping. TipTop is the most advanced,
easy-to-use telecommunication and terminal emulation program for
NEXTSTEP available today.

TipTop Software thanks all its customers for making the release of v1.5
possible. As always, our design is driven by your feedback.

The demo version is available by anonymous FTP from the

 o TipTop-1.5.tar.gz
 o TipTop-Supplement-1.5.tar.gz

Currently in The demo version runs
13 min at a time and has a limitation on file transfer size.

The main TipTop features include:

 o Easy to use GUI: Standard NEXTSTEP user interface features. The
   terminal window features a toolbar, a scrollback buffer, a find panel,
   changeable fonts, etc. Built-in PhoneBook and Inspector facilitate
   easy and convenient configuration of the communication
   parameters, window appearance, and other settings.
 o Terminal Emulation: ANSI, VT102, and VT220, all including ANSI
   color support.
 o Serial Ports/Shells: Multiple serial (modem) port connections and
   shell sessions. The UUCP locking protocol is used for serial ports.
 o Scripting: A powerful script programming language based on Tcl,
   Expect, and Objective C! The automatic script generator makes it
   easy to create basic scripts. [Among other things, the scripting
   language can run ``term'' which is used to establish a SLIP-like
   connection to a remote site. This allows several simultaneous
   terminal sessions to be connected to a remote site, while files are
   transferred and remote commands executed. One can even run
   remote X-window clients connected to the local X-server.]
 o Application Programmers Interface (API): TipTop's internal objects
   can be messaged from a script as well as from other applications.
 o File Transfer: Bundled transfer protocols include X-, Y-, and
   ZMODEM. Any external transfer protocol can be used with TipTop.
 o Key Bindings: Flexible keyboard mapping. Any key (with or without
   combinations of the Ctrl, Alt, and Shift modifiers) can be redefined
   as any character, string of characters, script, or even as an Objective
   C message!

New features in v1.5 include:

 o Loadable bundles allow end-users to extend TipTop without limits.
   For example, end-users can design their own objects, such as
   toolbars, dialog panels, etc. and fully integrate them into TipTop.
 o Remote serial port feature allows access of serial ports on any
   NEXTSTEP computer reachable through a network from TipTop,
   i.e., a remote modem session can be opened just as if the modem were
   directly attached to the local computer. The server machine, i.e.,
   machine to which the modem is physically attached, requires a
   TipTop Serial Port Server. The server will be released soon.
 o The API is greatly improved. It is now easy to design new toolbars,
   new session objects, new session panels, etc.
 o Many GUI improvements, including new Toolbar, Dial, and Term
 o ISO Latin 1 character encoding is included. Users can create their
   own character encodings.
 o Email transfer scripts allow email transport from and to
   through TipTop. When the deliver button is clicked in, the
   outgoing message gets queued. When the SendMail script is run, all
   the messages that are queued locally get transferred to the remote
   machine and sent to the appropriate recipient(s). When the GetMail
   script is run, all the messages stored in the remote mailbox get
   transferred to the local machine so that they can be read in This is very useful if one has a Unix account with email
   access, and no email access for the local NS machine. (These sample
   scripts are not supported by TipTop Software.)
 o And much, much more...

TipTop telecommunication software runs on Motorola, Intel, and HP
PA-RISC machines running NEXTSTEP 3.1 or higher. TipTop still costs
only $185 + S/H ($4 FirstClass Mail within US, $8 AirMail to Europe). Site
licenses are available as well as academic discounts.

Fax: (+) 972 3 695 3679



The Operator is a Graphical desktop manager based on Tcl/Tk. The idea is
to provide simple and intuitive User interface to most of the unix
commands. The Operator program is not only for software developers, but is
a general tool for any kind of users. The interpretive nature of the Tcl/Tk
gives it flexibilities that are mostly not found in other packages. It displays
directories and files in different ways in few independent windows. It
provides the user a friendly interface to the xterm command line interface,
with buttons and menus. The XTerm interface is also useful as Drag & Drop
target, what makes it sensitive to files, directories and Operations that the
user drop into it.


It is running (and was tested) on Linux (Slackware distribution 2.1.0) and
sun-Sparc-Solaris-2.3, 2.4. If you are running the Operator on other
platform, please drop me an e-mail letter that describes the system and any
problem that you had bringing it to work.


The Operator is available from different hosts on the internet. I put the
latest version on The administrator
probably moves the files into The site should have it also. Shareware diskettes and
cdroms from different publishers might have it. I'll provide a list in future
versions :-) In case you don 't have access to the above internet sites or a
copy of a sharewares disk (cdrom) with a copy of Operator you can get a
copy of the Operator-??.tgz file from anyone that has a copy of the file. You
can also use ftp mail servers to get a copy from the above sites. As a last

following as a subject line 'REQ: Operator copy' as a result I'll send you a
copy of the latest version of Operator through e-mail.


For the installation procedures please read the INSTALL file in the
distribution file.


The Operator is not public domain, it is a shareware. Please look at the file
COPYING in the Operator distribution for more information about using /
copying it . Thanks :-)

In short, one evaluation month, afterwards, $38.


I'm looking forward to hear your thoughts and ideas about this program.
Please feel free to send me mail (or fax) about the Operator software or any
part of the distribution files, including this document (English is not my first

VHDL Design Entry System

Usage: Electronic Design using VHDL
Company: SoftSmiths Pty. Ltd.
Contact: Geoff Smith

Product:     VHDLcapture
Description: VHDL & State Machine Design Entry  
             X11 based Design Entry Tools from SoftSmiths  


VHDLcapture is a general purpose design capture tool supporting the VHDL
language. VHDLcapture is a second generation development based on
SoftSmiths schematiX11-VHDL tools. The user interface has been been
completely rewritten in the Tcl/Tk language giving the user maximum
customization capability.

VHDLcapture allows five tasks to be performed:

 1. Graphical capture of state machines and automatic generation of
   synthesizable VHDL code from the state machine diagram.
 2. VHDL Behavi{*filter*}Definition of functional blocks.
 3. Datapath definition with pre-defined parameterized symbols.
 4. Hierarchical graphical capture of the interconnect of these
   functional blocks and/or predefined library elements.
 5. Automatic generation of VHDL structural netlists including support
   for multiple configuration statements.

Finite State Machine Generation

For blocks that can be defined as a state machine, VHDLcapture offers a
powerful tool for the graphical capture of state machines. The state
machine is defined in a flow chart style using state, conditional test and
signal assert symbols.

For simulation VHDLcapture can produce VHDL code that matches the
functionality of the graphical state machine. This VHDL code is compatible
with most known synthesizers.

Behavi{*filter*}VHDL - The VHDL Tool

Using graphical design entry the user may design high level VHDL blocks by
defining symbols and entering VHDL code for their functional description.

VHDLcapture provides rapid access to the functional code description for
each block. By simply clicking on the block, VHDLcapture finds and opens
the appropriate entity, architecture/configuration files using the editor of
your choice.

Being in a graphical form it is much simpler to transfer the design concepts
to other colleagues and allows direct browsing of the functional code for any
block at any level in the hierarchy.

Datapath Library

VHDLcapture comes with a library of parameterized datapath building
blocks. Simply place a unit, adjust its properties to suit, e.g. number of bits)
and interconnect the units with other datapath or user defined blocks.

VHDL Structural Netlists

Regardless of how the symbols are created, state machine, behavioral,
datapath or predefined library, these symbols may be graphically

Symbols may be hierarchical compositions of other symbols using the
general schematic features of the VHDLcapture product.

Facilities exist via the properties mechanism to set and modify VHDL
generic values and to set and modify port types.

VHDL code representing the structural interconnect of these designs are
automatically generated as part of the netlisting process.

The result is a collection of VHDL files that either define the structural
interconnect or define the behavior of the leaf level blocks of the hierarchy.

Simulation Interfaces

Simulation interfaces to MTI's V-System and Synthesia's MINT simulator
are directly provided. Or provide your own with Tcl/Tk customization.

Tcl/Tk Customization

The graphical user interface is designed with the Tcl/Tk script language
originally developed at Berkeley University. Tk provides the graphics and
Tcl is the script language that ties the interface to SoftSmiths C database.

From a user's perspective the real benefit is the ability to customize the tool
for their environment using an "industry standard" language. For example,
suppose you have a proprietary VHDL simulator, Tcl/Tk allows you to easily
add a menu and windows to give direct control of your simulator from
within the VHDLcapture tool.


VHDLcapture is available under very cost effective site licences that allow
UNIX based productivity at prices per user comparable to PC based products.

VHDLcapture runs on Sun Workstations (Sunos 4.1.3 & Solaris 2.4) and/or
attached X terminals. For more information please contact
