This is what a virtual machine is more or less.  Java's is the most =
famous, but there have been a couple virtual machines designed in Euphoria =
as well.
A virtual machine has the advantage of being able to write programs that =
are 100% portable without modification to any platform that runs the VM =
(virtual machine).  It also allows for functional enhancements over what =
the host processor may be capable of (byte codes for string math, for =
example).
The main disadvantage of VMs is their speed.  A host processor must spend =
several more cycles processing an instruction through the VM than if it =
handled the same instruction directly.  While it's theoretically possible =
to write a VM that would allow you to play MMX games on a 486 or other =
platform, the slowness of the VM in performing each MMX instruction on =
such a platform would make it not worth playing.

I'v got an idea for program that woud change history of computers.
Coud it bee posible to make a program that woud act like a procesor? So =
you coud play Qake 3 on 486 for example.
Iz is not necesary that the program woud bee made in EU.
You think that I am crazy. I am yust asking.
