TCL Programming

TCL stands for Tool Command Language. Tcl is both a scripting language, and an interpreter, which can be easily embeded into an application. Tcl and its associated graphical user interface toolkit, Tk, were designed and crafted by Professor John Ousterhout of the University of California, Berkeley. You can find these packages on the Internet (as explained later) and use them freely in your application, even if it is commercial. The Tcl interpreter has been ported from UNIX to DOS, Windows, OS/2, NT, and Macintosh environments. The Tk toolkit has been ported from the X window system to Windows and Macintosh.
