This course covers the fundamentals of the Tcl
programming language. You'll learn about Tcl commands, quoting
conventions and control structures before we move on to cover
topics such as strings, lists, arrays and regular expressions.
Further topics covered on the course include writing your own
commands (procs), packages, libraries, namespaces and other -
you'll leave the course with a thorough grounding in Tcl.
Tcl is often used as an embedded language, and we'll show
you how it's embedded within applications such as Expect, and
briefly how it's used in association with Tk.
This course is for delagate without prior programming
Getting the most from your Well House Consultants course
Tcl is a programming language that's used in a wide variety of
niche applications - ranging from Numerical Control Machines to Integrated
Cirsuit design. It's also very strong as an Engineer's language in system
testing, where the with the additional Expect extension provides a tool
that would be hard to better.
