I'm looking for some references on how a scripting program run so that
I can understand the runtime behavior better. But I don't find such a
reference. For example, I checked Programming Language Pragmatics by
Michael L. Scott. It seems only mentioned the programming language
that needs compilation.


Could somebody pointing me some reference on how a script is executed
so that I can understand the runtime behavior better?


Also, why the compiled code in java and perl are in general slower
than the equivalent code in C or C++?
[Because java and perl are compiled to internal forms that are then interpreted, or in
Java's case, sometimes translated at runtime. -John]
