Scripting language originally called '''Tool Command Language''' that unlike most other such languages is maintained and controlled by a single company that has a core version that is open source and sell more advanced versions as closed source commercial software. The convention is to call it Tcl rather than TCL since its name is now considered to be Tcl and not an acronym for Tool Command Language. Development of the language and toolkit was extremely rapid in the 1990's but has slowed down considerably in the last 15 years.

Extremely [[REXX]] like in structure.
Tcl is the Tool Command Language and Tk is the windowing Toolkit for Tcl. Originally designed as a macro- and initialization-file language for people's applications, the example applications tclsh (Tcl Shell) and wish (Windowing Shell, Tk) are nowadays most often used to run complete, portable script-applications. Tcl/Tk is officially supported on Unix and the X Window System, Apple Macintosh and MS Windows; user-contributed ports exist for e.g. VMS and, of course, OS/2.

====The Tcl War====
This was in its day a rather infamous flame war initiated by Richard Stallman of the Free Software Foundation who fired a somewhat incoherent rant on comp.lang.tcl telling people not to use Tcl. It turned out this was much like the famous Linux/Minix "Microkernel war" a rather cheap way of getting publicity by attacking what was perceived to be the most popular freeware product at the time. In this case it was to publicise two upcoming scripting languages the FSF had been working on in the form of [[Guile]] and another GNU product by now dead and buried. Unlike the "Microkernel War" were people overall had not enough knowledge about the subject to realise that it was essentially trolling on part of the flame war initiator, in this case most of the viewers had both knowledge and experience of multiple programming paradigms and were rather unimpressed with the initial argument (suhs as it was). This backfired somewhat in the face of the FSF as it generated a lot of positive noise about Tcl and negative ones about Guile, the FSF and Stallman.

The main advantage of the Tcl/Tk system on OS/2 has been the Tk widget toolkit and portability on systems where REXX is not common.

Tcl is the Tool Command Language and Tk is the windowing Toolkit for Tcl. Originally designed as a macro- and initialization-file language for people's applications, the example applications tclsh (Tcl Shell) and wish (Windowing Shell, Tk) are nowadays most often used to run complete, portable script-applications. Tcl/Tk is officially supported on Unix and the X Window System, Apple Macintosh and MS Windows; user-contributed ports exist for e.g. VMS and, of course, OS/2.
