The fundamental concepts of the Tool command language (Tcl) are introduced in this book. This book is for you if you want to learn a straightforward yet effective programming language.
The only prerequisite for reading this book is a basic understanding of programming in any language, including C, Python, Perl, and Lisp. If you understand what function and variable represent as well as other fundamental ideas, you shouldn't have any trouble moving on to the next chapter.
TCL: Why? Due to its simplicity and generality, it can be successfully utilized to construct applications in a short amount of time. You'll learn later that Tcl is a programmable programming language. There are a few concepts inside that can be combined to construct programs, and the language itself can be expanded to address programming issues directly.
