		   An Introduction to Tcl/Tk

			Stephen Edwards

Tcl/Tk form a powerful system for building interactive, graphical
applications.  Tcl is an embeddable scripting language, and Tk is a
set of user interface "widgets" such as menus, entries, and
scrollbars. I will describe the two packages, explain how they can be
used, propose some possible applications, and suggest how to get
started using them.

Tcl, "Tool Command Language," is a high-level interpreted language
created by Berkeley's (former) Prof. John Ousterhout that uses strings
as its primary datatype.  Its syntax resembles csh, and it can be used
like awk or perl.  However, its strength is its ability to be embedded
in other programs and easily extended with new commands written in C.

Tk, also by Ousterhout, is an X toolkit implemented in Tcl (i.e., a
set of new Tcl commands) that provides a very high-level interface to
such things as buttons, menus, scrollbars, and lists.  A few lines of
Tk code can replace hundreds of lines of C or C++.  Complete graphical
applications can be developed in minutes.

You may view the slides, which I created with Tcl/Tk, on an X
workstation with:
