[incr Tcl] for Windows

Tcl-object-oriented extension for free

The OO (object-oriented), system for the Tcl language, Incr Tcl is commonly known as [incr Tcl]. The language was first introduced in 1993 and has seen tremendous growth in the Tcl community. The incrTcl language is a play upon the C++ language. It provides additional language support to help build large Tcl/Tk apps.

Itcl can be downloaded on your Windows device free of charge. Before you download itcl, make sure your device is running Windows 7, Windows 8, Windows 8 or Windows 10. This extension is for those who know C++. If not, you can use Dev C++.

This language establishes that objects are building blocks for applications. The implementation can be used as a standalone language, or with its interpreter. It can also be loaded as a package by a Tcl program.

You can assign a variable in TCL using the command set. To get the value of a varible, a dollar sign is used. Strings are used to store the value of variables.

A loop is a repetition control structure that allows you to write code that can be executed a certain number of times. For loop syntax is:

For initialization, condition, increment, state(s);

To be able to use the control, you must understand its flow. The initialization step will only be performed once. A statement cannot be included here. The program will evaluate the condition and execute the code body if it is true. If the condition is false, the code will not run and flow control will jump to next statement after loop.

If the condition is true, and the body executes the loop will return to the increment step. This statement allows you to update the loop control variables and then the loop will reevaluate the condition. The loop will continue until the condition is false. After that, it will terminate.

Tcl's in-built commands 'Proc' allow you to create a new Tcl process called 'name'. It will replace any method that already has the same name. The Tcl interpreter will execute any contents in the body when you call the command.

Itcl is the most popular object-oriented system for Tcl. It is easy to use and allows you to offer an object model including variables and private classes.
