Excellent Free Tutorials to Learn Tcl

Tcl is a dynamic programming/scripting language based on concepts of Lisp, C, and Unix shells. 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.

The name Tcl is derived from “Tool Command Language” and is pronounced “tickle”. Tcl is a radically simple open-source interpreted programming language that provides common facilities such as variables, procedures, and control structures as well as many useful features that are not found in any other major language.

Tcl was created in 1988 by John Ousterhout and is distributed under a BSD style license. The first major GUI extension that works with Tcl is Tk, a toolkit that aims to rapid GUI development. That is why Tcl is now more commonly called Tcl/Tk.

Tcl is available for Linux, Windows, Mac OS X, as well as other platforms, as open-source software under BSD-like license, or as pre-built binaries.

Here’s our recommended tutorials to learn Tcl.
