Hi 2 All;


I will make some newbie questions; Plz. sorry about that.
I am making a tiny basic interpreter and I have seen that
there is two ways of do that :


1- The first one is to read the source and generate intermediate
          code; Then and Interpreter reads and executes the tokenized
          one.


2- The second one is to generate some kind of pseudo-Assembler,
          then a virtual machines reads and executes this.


I seems that actually the second method (VM) is the most popular. My
question is why?; When I generate a pseudo-Assembler that needs to be
interpreted and executed by the VM; I'am not creating another layer
that will slow down the execution?


If VM is the way to go, someone knows a page that shows the theory of
Virtual Machine design?


Thanx in Advance


Hugo
