The purpose of this document is to show
how the introductory programming examples from the book Python Scripting for
Computational Science can be implemented in Perl and Tcl. Topics covered
includes: Introduction to Tcl/Tk, A Scientific Hello World Script, Automating
Simulation and Visualization, Frequently Encountered Tasks, GUI Programming with
Tcl/Tk.
Tcl
is a scripting language created by John Ousterhout. It can be used
interactively, or by running scripts (programs) which can use a package system
for structuring, hence allowing to do much with little code. This book discusses
the GUI toolkit Tk in considerable extent, even though it's not in the title.
For most users, Tcl/Tk form a single conceptual entity.
