Course SummaryThe Tool Command Language was designed as a scripting interpretor to be embedded in C applications, allowing customizations and modifications of that applicat ion. Tcl is commonly used as a wrapper or control language in engineering design applications. Through use of a Tcl shell program, you can write general stand a lone Tcl scripts, thus allowing it to be used as a general purpose programming l anguage. One of the major Tcl applications is the TK toolkit, which allows for rapid GU I development. TK is covered in a separate course.
Audience:Anyone having a need to write Tcl scripts to customize or extend an application. Also anyone that wants to use Tcl for its rapid prototyping or simple application writing ability when combined with the TK toolkit, or other powerful Tcl applications such as Expect.
Prerequisite Knowledge:A programming background of any kind is helpful, though not needed.
Terminal Objectives:Upon successful completion of this course the student will be able to:
design, write, debug and test Tcl scripts that will run in a Tcl interpretor.
Course Length:1 to 3 Days, depending upon student experience, and level of Tcl skills required.
