Introduction to Tcl Programming Language
Introduction to Tcl Programming Language Introduction Tcl was originally intended to be a reusable command language. Its developers had been creating a number of interactive tools, each requiring its own command language. Since they were more interested in the tools themselves than the command languages they would employ, these command languages were constructed quickly, without regard to proper design. After implementing several such "quick-and-dirty" command languages and experiencing problems with each one, they decided to concentrate on implementing a general-purpose, robust command language that could easily be integrated into new applications. Thus Tcl (Tool Command Language) was born. Since that time, Tcl has been widely used as a scripting language. In most cases, Tcl is used in combination with the Tk ("Tool Kit") library, a set of commands and procedures that make it relatively easy to program graphical user interfaces in Tcl. On
