DDE 2.0 Package for Tcl/Tk

Overview

	This package provides a full featured interface to the Microsoft Windows
Dynamic Data Exchange Management Library (DDEML) API from a Tcl interpreter.
The package consists of a dynamically loaded extension to Tcl, a help file that
covers the features of the package, and some demonstration scripts.

Installation

	The install.exe application will perform a standard installation for you. The
installer puts the package files in the directory that corresponds to the $tcl_library/dde
path. If you don't already have Tcl/Tk    installed, you should install it before you
try to install this package.

	The installer checks for the environment variable TCL_LIBRARY. If this variable
is not in your environment, then you probably have not installed Tcl/Tk properly. The
installer will then use a default value, which will probably require you to specify
a complete path to any scrips you use, and make it necessary to edit the paths in the
script files to point to where you do the installation.

Running the demonstration scripts

	The scripts work with Tk using wish, or some similar extension such as Tix or your
own customized version of wish. After installation, start the scripts using a command
of the form

			wish [path]name.tcl

or, alternately, start wish and use the source command to load a script. 

The installer will create a program group with all the demonstration scripts set up 
so that a double click should run them, unless there were complications during the 
installation process.

Help Information

	If the package is correctly installed, the first time you load the extension, the
help file will be started up. Go through it to see what can be done and how the scripts
can be loaded and run. Esit the "loaddde.tcl" script to supress loading of the help
file if you don't wish to see this information.

	The help database was generated under Windows95, so if you are using this package
under Win32s, your help file viewer (WINHELP.EXE) may not recognize the help file. If this
is the case, you need to get a version 4.0 viewer. These come with Windows 95 and later,
and are probably available from Microsoft.

	If you register as a user, and need an old format help file, one will be sent to
you via e-mail, or some other electronic method, on request. See the registration
information to find out where to send the request.

	Registered users will receive support via electronic means if they request it. 
Others will get no help at all. Be sure to include an e-mail address if you register and
anticipate that you may need support. My 2 year old answers the phone, so I advise against
using this medium.

Future Developments

	I plan to extend this package to include an interface to UINX based interps running in
a networked environment.

	Other suggestions are welcome.
