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/tests. 

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

--------------------------------- 

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

Usage: Computational Fluid Dynamics Applications
Company: ICEM CFD Engineering, Berkeley CA
Contact: Wayne A. Christopher
Email: wayne@pmac.com

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
simulation. 

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.

Unix 

TCL/Tk;
-------

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
Email: gwl@cpu.com

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

CPU has embraced Tcl/Tk technology and made it the basis for its own
powerful SCADA 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. The user must furnish
applications (including the GUI) to build the completed SCADA system.
CPU has brought all of RTAP s API (i.e., call interface) up into Tcl as Tcl
commands. The GUI and application programs are written in SCL Plus
(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 located in the Gulf of Mexico. Shell Offshore
Incorporated s tension-leg platform, Auger, is 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 effort for SCL Plus and this facility has 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
Email: alex@system9.unisys.com

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
environment. 

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
market.

P7. - Cyberterm - a Networked 3D OS for PCs 
============================================

Usage: Cyberterm - a Networked 3D OS for PCs
Company: Cyberterm Pty Ltd
Contact: Michael Snoswell
Email: snoswell@guest.adelaide.edu.au

Cyberterm 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
cyberspace. 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).

NANNY
=====

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.

KIS
===

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

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
NetBlazers. 

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,
   and 
 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

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! 

Requirements
============

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. 

OPTIONS:
========

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! 

FEATURES:
=========

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. 

AVAILABILITY:
=============

Multi Player SimCity is available directly from DUX Software, and via 
anonymous ftp from ftp.uu.net (192.48.96.9), 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!

ENTRY P15. - Sibylla 
=====================

Usage:Tcl based World-Wide Web application development framework
Company: Ariadne Engineering, 27020 Torre d'Isola (PV), Italy.

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. 

SUPPORTED PLATFORM 
===================

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. 

SOFTWARE VERSIONS 
==================

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
   standard 
 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
applications: 

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

Functions 
----------

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
system. 

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
spreadsheet. 

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.

Tcl/Tk Interface for XESS Spreadsheet Simplifies Application
============================================================
Development 
============

Applied Information Systems has tclXess, a Tcl/Tk interface for its XESS
spreadsheet product under Unix and OpenVMS. This makes it easier to
construct advanced applications which integrate the XESS spreadsheet with
other products. AIS has placed the sources for tclXess online in the Tcl
archives at ftp.aud.alcatel.com:/tcl and at ftp.uu.net:/vendor/ais in the file
tclXess-1.0.0B.tar.gz. 

The tclXess interface between XESS and Tcl/Tk is derived from work done
at General Electric Corporate Research and Development under DARPA
contract MDA972-88-C-0047. AIS will provide continuing development
and support of this interface software.

ENTRY T1. - Object Oriented Programming with [incr Tcl] 
========================================================

Usage: Training
Company: AT&T Bell Laboratories
Contact: Michael J. McLennan
Email: michael.mclennan@att.com

Course Title: 
   Object-Oriented Programming with [incr Tcl] 
Course Length: 
   2 Days 
Course Format: 
   Course material is presented in a lecture format. 
Course Description: 
   When Tcl/Tk scripts grow larger than a few hundred lines, the code
   complexity can be difficult to manage. [incr Tcl] provides a set of
   object-oriented extensions for the Tcl language, enabling
   programmers to write high-level building blocks that are more easily
   assembled into a finished application. This course describes
   object-oriented programming with [incr Tcl]. Fundamental
   concepts are presented on the first day, showing how [incr Tcl] can
   be used to write more modular code. On the second day, these same
   concepts are used to create "mega-widgets", high-level widgets that
   look and act like the usual Tk widgets but are constructed entirely
   with [incr Tcl] code. 

Topics include: 

    o Designing object classes 
    o Public/protected data members 
    o Shared data members 
    o Member functions (methods) 
    o Inheritance 
    o Multiple inheritance 
    o Object construction/destruction 
    o Manipulating scope 
    o Persistent objects 
    o Anatomy of a mega-widget 
    o A mega-widget base class 
    o Example widgets 
    o Adding new bindings 
    o Creating reusable libraries 
   Course Level 
      Technical: Beginner to Intermediate 
   Prerequisites 
      Exposure to tcl/tk programming concepts

ENTRY T5. - Tcl and Tk: An Applications-Based Approach 
=======================================================

Usage: Training
Company: NeoSoft
Contact: Karl Lehenbauer
Email: sales@NeoSoft.com.

NeoSoft Tcl and Tk Training Information
=======================================

NeoSoft is perhaps the premier corporate contributor to the Tcl and Tk
toolkit efforts. Our groundbreaking work in Tcl and Tk dates back to its first
appearance in 1990, and is reflected by the copious amount of concepts and
code taken from Extended Tcl for use in the Tcl baseline. We continue to
collaborate with Dr. John Ousterhout, the author of baseline Tcl and Tk, on
the forthcoming release of Tcl 7.0 and Extended Tcl 7.0. 

NeoSoft's Tcl training efforts have been a natural outgrowth of our work
with, and extensions of, Tcl. 

The philosophy of the course is one of immediate, maximum impact by
rapid immersion into hands-on building of X-windows graphical user
interfaces and the Tcl programs that underly a number of useful
applications. This approach grew out of our first-generation Tcl training
course, where we discovered that students became very excited once the Tk
toolkit was introduced and they could begin typing statements and
interactively creating sophisticated X-windows interfaces. 

This same philosophy is the backbone of a book we're writing, Tcl and Tk:
An Applications-Based Approach, due to be published in the first quarter
of 1994 by Prentice-Hall Technical Publications. 

Training Options
================

We are flexible and can customize a course to your specific needs. We have
found that almost everyone is content with one of a few options. The class
lasts for two or three days, at your option. The class can be structured to
support new Tcl and Tk users and/or users with significant prior experience.
In either case, it is nice to allocate some unstructured time at the end of the
class to talk about specific applications and issues that the students are
interested in, including new users, approaches, tools, environments, and the
future of Tcl itself. 

Course Location and Times
=========================

The course can be taught at your company's facility, or at our training
facility located in Houston, Texas. Enrollment is limited to ten people per
class to provide a substantial amount of instructor attention to each student.
If the course it to be held at your company's facility, there should be no less
than one workstation per two students, if at all possible. The class can be
taught over a weekend. Contact NeoSoft for pricing and availability. 

Instructor
==========

The class will be taught by Karl Lehenbauer, the co-author of Extended Tcl.
Karl is an experienced trainer, having taught and/or developed previous
courses on Unix, Unix system administration and Tcl/Tk. 

Course Goals
============

Teach Tcl and Tk with the maximum impact by building real world
applications in the classroom. 

Site Prerequisites
==================

Integrated copy of Tcl and Tk, including Extended Tcl, running on site. 

Course Contents
===============

Below is the list of basic sections of the class, beginning with the elementary
