Tool Command Language
Tool Command Language
(language)Tcl is like a text-oriented Lisp, but lets you writealgebraic expressions for simplicity and to avoid scaringpeople away. Though originally designed to be a "scriptinglanguage" rather than for serious programming, Tcl has beenused successfully for programs with hundreds of thousands oflines.
It has a peculiar but simple syntax. It may be used as anembedded interpreter in application programs. It hasexceptions and packages (called libraries), name-spacesfor procedures and variables, and provide/require. Itsupports dynamic loading of object code. It is eight-bit clean. It has only three variable types: strings, lists andassociative arrays but no structures.
Tcl and its associated GUI toolkit, Tk run on allflavors of Unix, Microsoft Windows, Macintosh and VMS.Tcl runs on the Amiga and many other platforms.
Latest version: 8.0.3, as of 1998-09-25.
