Tool Command Language

More about Tcl

Tcl stands for “Tool Command Language.”
It was created by Dr. John Ousterhout from the University of California, Berkeley, primarily for issuing commands to interactive programs such as text editors, debuggers, illustrators, and shells. Tcl is one of the most cryptic of the new computer languages and the syntax appears even more low-level than the C language.
Tcl is also a library package that can be embedded in application programs. The Tcl library consists of a parser for the Tcl language, routines to implement the Tcl built-in functions, and procedures that allow each application to extend Tcl with additional commands specific to that application. Tcl is an interpreted language that is not compiled. The application program generates Tcl commands and passes them to the Tcl parser for execution. When the Tcl library receives commands it parses them into component fields and executes built-in commands directly. For more information about Tcl, visit the following Web sites:
