Tcl
is a scripting language created by John Ousterhout. It can be used
interactively, or by running scripts (programs) which can use a package system
for structuring, hence allowing to do much with little code. This book discusses
the GUI toolkit Tk in considerable extent, even though it's not in the title.
For most users, Tcl/Tk form a single conceptual entity.
This note introduces the basics of Tcl. Chapter1
describes the fundamental properties of the language. Chapter 2 is a short
introduction to running Tcl and Tk on UNIX, Windows and Macintosh systems.
Chapter 3 presents a sample application, a CGI script, that implements a
guestbook for a Web site. The rest of this book covers basic programming with
Tcl.
