[Explain embedding a scripting engine in existing application to achieve flexible combination of fixed elements. This raises questions: which scripting engine to embed? How to do so? What does this make possible?]
[Three examples of approach in conventional Java-oriented application development: "Tcl your Java apps" [L1 ] and "Tips for Scripting Java with Jython" http://www.onjava.com/pub/a/onjava/2002/03/27/jython.html ] and, by same author, "Introduction to Jython" [L2 ].]
[Much need interesting write-up of hardware-oriented embedded examples--space shots, submarines, factory controllers, ...]
Scripting vs. programming: I'm not sure whether there is a clear distinction - certainly you can do both in Tcl. Maybe the following criteria make sense (RS):
Hmm, not really, since scripting really finds its strength in convenience and brevity of code, not really in lack of organization or proper method ;) - IL
Unfortunately, management in some companies make the distinguishment of scripting == trivial work versus programming (in a real language) == work worthy of promotion and raise
"Adding Tcl/Tk to a C application" is important reading that explains the inapplicability of common scripting notions.

"Why Scripting" touches on the value of "dual-level" programming.
We call them Dynamic Languages now. :-)
