Tcl (Tool Command Language) is a scripting language originally designed for embedded system platforms. Since its creation, Tcl has grown far beyond its original design with numerous expansions and additions (such as the graphical Took Kit or Tk) to become a full-featured scripted programming language capable of creating elegant, cross-platform solutions.

In this article by Bert Wheeler, author of Tcl/Tk 8.5 Programming Cookbook, we will cover the following topics:

  • The Tcl shell
  • Writing to the Tcl console
  • Mathematical expressions
