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
- Tcl expr operands
- Tcl expr operators
- Mathematical functions
- Computing mathematical expressions
- Referencing files in Tcl
- Variables
- Launching a Tcl script
