This article presents information related to the computer software Tool Command Language/Tool Kit (Tcl/Tk). It is a scripting language for coding embedded applications. Tcl is supplied and supported by IBM, Sun, Hewlett-Packard, and the major Linux distributors. Creator John Ousterhout spun his own Tcl company off from Sun, and tools and services for Tcl are now provided by Active State, a division of anti-virus company Sophos. However, the vigour behind the language comes from the open source community, in networking, mobile telecoms, software testing, Unix software houses, banking and healthcare. Tcl runs on Windows, Linux, most Unix platforms and Mac. Experienced programmers can learn Tcl and produce their first application in just a few hours, and it is also suitable for casual programmers. According to Ousterhout the simplest introduction is to take an existing program that was not written to have a GUI, wrap it up in Tcl, and put a GUI on it. One can download the productivity toolkit Tclpro in its open source form free at www.tcl.tk. It is also sold as Tcl Devkit by Active State. INSETS: Rates of pay;Training.
