This is a very short introduction to the Tcl script language. If you just can’t wait, I hope this will make you able to read and to understand simple Tcl code.
In many points, Tcl is similar to C, especially for loop structures, function definitions and mathematical or conditional expressions. In other points, such as expression evaluation and list data structures, you will notice that Tcl has inherited from the benefits of the Scheme language.
In Tcl, all data is represented as strings.
